Defender 2009 is a rogue security program that wants users to believe it is capable of removing spyware, viruses, parasites and other security threats from their PC. Hackers design these malicious applications in hopes of frightening you enough that you will purchase their product. This one is not capable of doing anything, except perhaps causing harm to your computer or personal identity.

This trick has been used thousands of times under many different names. There are legitimate antispyware tools available, but Defender 2009 is not one of them. This program is not capable of scanning your computer to start with, and it certainly will not detect or remove any infection that may (or may not) exist. Usually, trojans are responsible for installing these infections on your PC without your knowledge or consent. Most come from other files you may download such as music, games or videos. You might also become a victim by clicking links in spam emails, or visiting questionable websites.

These applications can pose a real threat not only to the health of your PC, but your personal identity as well. They are capable of collecting information about the websites you visit, the searches you perform, and your personal passwords, credit card numbers and other business data that you want to be private. They may sell this information to third parties as well. Although you don't realize the moment Defender 2009 becomes placed on your PC, you will begin to see the symptoms shortly after.

Some of these symptoms include system instability, a slowing of your computer, freezing, pop-up ads and browser redirection. You will notice that your PC simply is not acting normal. When this happens, you must remove these parasites immediately. You may attempt to remove these applications manually by deleting all of the related files, but this is extremely difficult to do for most people. In fact, if not done properly it can cause additional damage to your computer.

If you believe that Defender 2009 has been installed on your PC, the best thing you can do is use a legitimate antispyware program to scan your computer for viruses, trojans and other security threats. Get one that guarantees to remove 100% of infections with one scan, and rest assured that your PC will once again be secure.

To scan your pc for free and find out if you have Defender 2009 click here.

Nowadays many people on various forums complain, that their favorite web-sites are blocked either at work, at school or even in the whole country. Some people, for example, from China, may have a wish to watch video-news at British BBC. They can't, since these videos are available only if they are physically in Great Britain. All these people are looking for proxy . Most of them, of course, prefer free proxy.

Proxy is believed to provide not only access to something blocked, but also some kind of anonymity. When you serf through proxy server, your IP is replaced by proxy-IP (note, that it doesn't concern transparent proxy). But if you have tried free public proxy at least for one time, you definitely know how slow they are. This is because they are used by hundreds or even thousands people. Using web-proxies, you have to see bulk of ads. Sometimes you even click on them, while waiting for a connection, and spend your precious time in vain.

Moreover, free proxies have a tendency to have a quite short life. This is due to the way they are created. For example, lots of http proxies (proxy server, that you can reach through ip-address) are created by mistake of system administrator and then found by robots and included in lists. When the administrator discover this, he correct the mistake - and there is no more proxy on this address. Another way of proxy beginnings is it's creation by hackers. While you use this kind of proxy, they stole your information, getting access to your computer. This kind of proxy are compensated from stolen credit carts, so they shut down, when it becomes discovered.

The most important thing you need to know if you want to use free proxy is the danger to your security. When hackers set up an open proxy, it is called a 'Hacker Pot'. It comes from a similar term a 'Honey Pot' (a server, set up by government agencies or security professionals, to entrap people who are looking for free proxies, as far as they can be hackers). Such machines are used to track down hackers. However, even if all you want to do is unblock your favorite social site, you have reason to be concerned. Because unauthorized access to this machine is already a federal felony. They don't have to announce to you that this machine is a government computer. It's your responsibility to know where you are connecting to.

So where is the right decision? If you still need proxy for legal purposes - the only secure way is to use elite premium proxies Using this kind of proxy servers you can be certain, that you will have stable connection and speed, as far as they are used by only a few people, who have login and password. If you use socks5 proxy, you can not only surf the net, but also use almost all programs, that require internet connection (at least with the help of special programs like Sockscap). And, of course, replace your real IP to get the highest level of anonymity. Premium servers have no reasons to stole your information as far as you pay them. This money are not so big, comparing to your stolen identity or problems with law.

Now a day everybody have computer in their house for their personal use. So for that they need internet connection, because without internet there is no meaning of computer. Many people have relatively simple needs for their home networks. Even now that many computers within a single home are common, the systems are frequently not networked, with file transmit being done by means of sneaker net, or copying files to and from a CD or by transferring files using email.

This is a best time to construct your own home network, if you have forever wanted to. The expenses and the difficulty of the systems are lower than ever. Just getting past the technical terms used is the biggest wall for many new home network builders. The tools you will need are very easy to get. You are going to require Cat-5 or Ethernet network cabling for a wired network. Imagine about where you plan to set up your computers to decide how much cable you are going to need and then add on about 1/5 more cable than that you always require a little more than you think Before the days of networking this was one of the most excellent ways to fix computers together and is still used on UNIX machines as a primary method of connecting to cheer up. These are a latest standard of transmitting audio down a fiber optic cable. Mostly used by Dolby enclose sound systems and new laptops. USB Cable first and foremost used for the latest standard of printing. One can even do USB to USB LAN links. There are now two versions, USB1 and USB2. USB1 being 12MBps transfer speed whereas USB2 runs at 480MBps (mbps is the Mega Bits for each second transfer speed).

Domestic PC Cables connect devices within the actual computer to the main board that is motherboard. The slowest connection speed being used by the floppy cable then the IDE cable which attaches the hard drive. SATA (Serial ATA) cables have now go beyond the IDE cable as the primary method of connecting a hard drive to a motherboard. SCSI cables usually are only used in servers for connecting the SCSI hard drives. Network Cables, There are two types of Network cables, Cat5e and Cat6e. Inside these two types there are two formats, straight through (standard) and crossed. The difference being that straight through standard used in common networks all through companies and is used for connecting computers to network wall sockets and from network patch panels to network switches. For lesser networks, i.e. two computers, a intersect cable is used among two computers which have net cards to permit them to talk to each other. Difference between the speed Cat5e and Cat6e is generally thought to be 100MBps for Cat5e and 1000MBps for Cat6e network cables. Although in reality Cat5e can run at 1000MBps but is not correctly protected to do so.

'Network is the OS', considering this as a motto major vendors are working out to release products that will be out in near future. Right now majority of users can use their computers with or without an internet connection. But most of the SME businesses have operations spanned across various locations with need to address the issues arising from computer networks. One such evolution of technology is to optimize wide area network. This article will give you a picture of causes for WAN Optimization Technology.

Causes

There are some proven concepts that create a dent on budget for IT infrastructure of businesses. What are they?

  1. Network Latency
  2. Lower Bandwidth
  3. Chatty Protocols
  4. Application Performance
  5. Pocket Loss

Network Latency

Latency can be meaured by Roundtrip time (RTT) which is the time taken for a request from the client and response from the server. A best example of low latency network is your Local Area Network or LAN where the distance between your PC and the response server is relatively low with a minimal set of network hardwares installed on the path. The RTT increases as the distance between the requester & responder increase alongwith more number of intermediate networking devices. A higher latency network always result in a decrease in throughput.

Lower Bandwidth

Capacity of any link is denoted by its bandwidth. A higher bandwidth link costs more because of its potential to handle larger transfer rates and negligible outage. Example of higher bandwidth is Optical Fibre (OF) and DS3. A limited bandwidth link of fewer kbps installed in any of the branch locations cannot support the requirement of a large data transfer with other locations. Examples of lower bandwidth are Frame Relay, ATM, MPLS, Cellular and Satellite networks.

Chatty Protocols

Some protocols take longer time to respond on the user side. Chatty protocols use multiple communications between the ends for a single request. It takes more time to establish a connection before starting any transfer of data. This results to a lower throughput and under utilization of network bandwidth. Few of the chatty protocols are TCP, HTTP, CIFS and FTP.

Application Performance

An efficient organization needs wide variety applications to be deployed to increase the productivity. Employees of those organization need access to applications installed on other locations at greater speed as they are available on the LAN. Performance of applications deter because of clogged network and reduced throughput. One cannot be sure of which application uses higher bandwidth and which does not unless they have deployed Quality of Service (QoS) on their network gateway. There is not much control over applications like email, storage/backup, ftp that use sheer volume of data and the need to communicate between the ends must be maintained over a WAN.

Pocket Loss

A higher bandwidth usage over a WAN could result to an increase in pocket loss. Few protocols reduce the transmission speed to counter the pocket loss and resulting in under utilization of bandwidth. Often content streaming like audio / video ares affected by pocket loss.

WAN Optimization has breached the US $1bn barrier and is growing on an average of more than 20% year-on-year. For a distributed environment business continuity and disaster recovery, wan optimization is a must to implement technology to maintain a high quality network. There are more number of vendors with products and solutions looking for customers to address the above discussed issues and with more specific solutions for all industry verticals. Marketing could hide the fact, but as a business partner you need to gain knowledge on the technology and profit your business.

Do you know what the difference is between a champion and an outsider? A winner has an ambition to win and gives all their commitment and dedication to victory. The formula of success in 99% of the cases is with this spirit of fighting and onward victory. You can apply this key method in any sphere, activity or field. Today I would like to provide you with some interesting information on satellite internet. What makes satellite internet so attractive nowadays?

1. Every day the beautiful world of sound, in other words music makes our life much happier. Maybe you aspire to be a professional singer or an amateur guitar player? In aspiring to any of these variants, music will surround you almost everywhere. An Internet satellite can give fast access to any portal of music where you can find musical samples of your favorite singers, players, performances, shows, recent events as well as forthcoming competitions and contests. This make you a really lucky person as you can use all the advantages of satellite internet connectivity that the 21st century allows, listening to the best music recordings literally anywhere in the world.

2. Cinematography is a most emotionally powerful and artistic medium. Whether you are a graduate of Film College or just a person who is fond of filmmaking, film producing and other interesting things with regard to the movie industry, then satellite internet is the resource for you. As you can find all manners of prize- winners, Oscar awarding ceremonies; the rarest collection of movie downloads at the click of a button. If you are ready for this world of unlimited cinematography, then this type connectivity is for you.

3. Let us examine the usages within profession of the performing arts. This is a very complex, difficult and challenging occupation. At the first sight it seems very easy for those who do not understand it. Actors, actresses, singers, artists, performers all need to place their profiles into the waters of the internet. As in advertising and promoting themselves, artists need to find good contracts, art directors or casting impresarios. They need to build up a good profile, showing all their talents, abilities and skills and to do this best they need fast resources. Thus this fast medium of access allows for the fresh talented tomorrows stars to begin their careers in the internet.

4. The written or spoken word was at the beginning our everyday means of communication as it was based on a common language. Writing is the springboard for our souls and minds. Thus human kind can develop its way of thinking as well as to raise its spirits by means of communications. Who knows may be you are the next famous writer like J.K. Rowling. If you are a literary critic, then you need for sure a book portal like Google Book services. As it is such a great opportunity to read masterpieces sitting in your chair and drinking cup of tea not having to go to the library... comparing classics, discussing and debating. Read Dostoyevsky or Fitzgerald using online satellite internet materials.

5. Employment is another benefit you can take from satellite internet. If you have a well trained and good educational background, or a broad experience and have a strong desire to share it with your international colleagues, you can source and then move to another job market which goes well with your aspiration and ambitions.

Servers are usually called as masters and boss in client server computing as it provides services to the clients. Clients are low graded machines compared to the servers, which usually requests to the server for getting a service. In general, a server passively awaits for the client to request, and it is server’s decision to provide a service to the client. For example, a file server is a computer and storage device dedicated to storing files Any user on the network can store files on the server.

Clients requests to the servers in the form of messages. These messages describes the server that, what kind of service is requested, and from which of the clients.

Here service refer to certain processes, like data transaction in case of a database server. According to the services provided by the server, we categorize servers into different types. They are:-

  • File servers
  • Database servers
  • Transaction servers
  • Groupware servers
  • Web servers

The above are the main categories of servers in client server computing. servers are usually fat, [high powered then clients] because they have to provide services for all the clients that are connected to it through any medium of network. In this case, its called as 'fat server' - 'thin client' atmosphere. In some cases, the clients do their own processes without any help from the server. these clients need server only for data clarification, in this case the atmosphere is described as 'fat server- fat client' atmosphere.

A fat client or rich client is a computer in client server architecture networks which typically provides rich functionality independently of the central server.

A thin client (sometimes also called a lean or slim client) is a client computer or client software in client server architecture networks which depends primarily on the central server for processing activities, and mainly focuses on conveying input and output between the user and the remote server. In contrast, a thick or fat client does as much processing as possible and passes only data for communications and storage to the server.

The server is almost hi-powered or equally powered to the clients that are connected to it. With this client server architechture, a long run of mainframes have came to end. Its only because of high cost and high care needed for a mainframe to run continously, but maintaining the server in client server architechture is very easy when compared to mainframes.

I've got good news for you. For years, we've been subjected to the tyranny of insolent cybercafe operators in various cities across this country. They charged ridiculous rates per hour yet delivered snail speed browsing.

Worst of all, your sensitive data weren't completely secure with some of them. I went to a cybercafe to browse one day and after about ten minutes, PHCN struck as usual. Not having reliable UPS, all the systems went off. After the generator was switched on, the systems had to go through a reboot.

But with the coming of the major GSM networks, MTN, ZAIN, GLO and others, the number of subscribers exploded to over 50 million. Currently, there is a surge in demand in mobile internet access which has been made possible by various packet data access technologies like GPRS, 3G, and HSPDA.

The most surprising thing at the moment is that the cost of access has also gone down dramatically. This means that in countries like Nigeria where about 8 years of democracy has led to the emergence of a new middle class, anybody with a pc or laptop with an appropriate mobile phone can now chat, browse websites, check email, trade stocks, and take online classes even in remote rural areas.

Basic Requirements For Connection

1. A GSM phone with GPRS/EDGE for normal speed Internet or a phone that supports 3G or HSDPA [high speed downlink packet access] for high speed Internet.

2. The phone's USB cable and its drivers [these usually come with the phone but can be purchased separately] or alternatively, a bluetooth USB adapter for PCs and laptop without native Bluetooth.

Benefits of Having Your Own Fast But Free Internet Access.

1. Read your favorite newspapers online [both foreign and local].

2. Download ebooks, videos and softwares.

3. Visit your favorite forums and post as well read other people's posts.

4. Browse the planet from the comfort of your room.

5. Check emails, fill forms, search for jobs, and chat on yahoo!, msn, skype, and aol.

6. Trade forex and monitor your stocks, news and the weather.

7. Take free online classes on various subjects that interest you.

8. Access the Internet even if you live in the remotest village in this country.

9. Make money helping students in your community register for WAEC, NECO, JAMB, POST UME and other examinations as well check the results.

10. Suitable for lawyers, doctors, bankers and other professionals who want to keep abreast of developments in their careers.

11. Can be used to access and print recharge card vouchers for MTN, GLO, ZAIN, STARCOMMS, RELTEL, etc fast and securely after you've registered with

Gartner’s Inc. independent research had shown that as much as half of network problems in the healthcare industry are due to an inadequate or substandard cabling infrastructure.

The network infrastructure represents the backbone supporting most IT functions. Today’s healthcare centers’ networks need to accommodate not only an enormous volume of data generated by the modernizations that technology brought to medicine but also need to comply with regulatory standards.

Telecommunications Industry Association’s (TIA’s), TR-42.1 Engineering Subcommittee formed in 2004 a task force group with the mission of bringing awareness within the healthcare industry of the benefits of having a comprehensive strategy for structured cabling design and installation that is unique to this industry. Most seasoned structured cabling contractors are aware that TR-42.1’s developing guidelines. These guidelines are meant to assure that telecommunications infrastructures for the health-care industry are adequate and universal.

Some of the areas covered in the guidelines TR-42.1 are listed below:

  • Voice, data, video network infrastructure cabling, (i.e. security alerts and surveillance, CCTV, and CATV);
  • Professional, patient and asset information systems and tracking;
  • Remote consultation/telemedicine, diagnostic imaging, digital transfer of X-rays, pharma applications;
  • Mobile applications including nurse call and patient monitoring;
  • Bio-analytical systems, clinical equipment monitoring, lighting control;
  • Fire and life safety systems, (i.e. alarms, sprinkler systems, Master clock);
  • Public network; and others.
  • The cabling infrastructure is critical in designing networks that are flexible, fully integrated and accessible. In today’s healthcare environment Ethernet networks that are IP-based are most suitable to provide the transmission of the large quantities of healthcare related data in a rapid and accurate manner. They support the many applications such as voice, data, video, monitoring and control.

    Transmission speed and bandwidth are important factors that determine a “high performing” network. Having a robust network infrastructure is more than a mere necessity. In healthcare facilities a network that fails can lead to far bigger problems than poor network performance, it can be life threatening. Gartner Inc. research firm concludes that "The wiring plant is arguably the most important part of the network. Spend the time and money to ensure that what is installed will be able to support the environment well into the future. ..."

    Considering that hospitals are built to last for more than 50 years the cable plant needs to be built to perform adequately for its lifecycle of about 10 years. Gartner research has shown that cabling infrastructure represents a very small percent of the IT designated resources (around 2%-5%) yet it can account for up to fifty percent of the problems. This demonstrates that an incremental increase in cabling investment can lead to an exponential increase in network performance, robustness/reliability as well as productivity and patient safety, patient safety being a major driver of the healthcare facilities network design.

    Given these statistics hospitals in North America should project and plan for the total cost of ownership of the network infrastructure over its expected lifespan, rather than initial installation costs as well as consider hiring contractors that comply or exceed the TIA’s TR-42.1 guidelines.

    A wireless LAN (WLAN) is a wireless Local Area Network that links two or more computers or devices using spread-spectrum or OFDM modulation technology based to enable communication between devices in a limited area. This gives users the mobility to move around within a broad coverage area and still be connected to the network.

    For the home user, wireless has become popular due to ease of installation, and location freedom with the gaining popularity of laptops. Public businesses such as coffee shops or malls have begun to offer wireless access to their customers; some are even provided as a free service. Large wireless network projects are being put up in many major cities: New York City, for instance, has begun a pilot program to cover all five boroughs of the city with wireless Internet access.

    Some wireless data networks run over wireless voice networks, such as mobile telephone networks. For example CPDP (Cellular Digital Packet Data), HSCSD (High Speed Circuit Switched Data), PDC-P (Packet Data Cellular) and GPRS (General Packet Radio Service). Other wireless networks run on their own physical layer networks, utilizing anything from antennas built into handheld devices to large antennas mounted on towers. 802.11 (Wi-Fi), LMDS (Local Multipoint Distribution Service) and MMDS (Multichannel Multipoint Distribution Service) are examples. A few wireless networks are intended only to connect small devices over short distances. Bluetooth is an example.

    Types:

    CPDP:

    CDPD (Cellular Digital Packet Data) is a specification for supporting wireless access the Internet and other public packet-switched networks over cellular telephone networks. CDPD supports TCP/IP and Connectionless Network Protocol (CLNP). CDPD utilizes the RC4 stream cipher with 40 bit keys for encryption.CDPD is defined in the IS-732 standard.

    HSCSD:

    HSCSD (High Speed Circuit Switched Data) is a specification for data transfer over GSM networks. HSCSD utilizes up to four 9.6Kb or 14.4Kb time slots, for a total bandwidth of 38.4Kb or 57.6Kb.

    14.4Kb time slots are only available on GSM networks that operate at 1,800MHz. 900 MHz GSM networks are limited to 9.6Kb time slots. Therefore, HSCSD is limited to 38.4Kbps on 900 MHz GSM networks. HSCSD can only achieve 57.6Kbps on 1,800 MHz GSM networks.

    PDC-P:

    PDC-P (Packet Data Cellular) is a packet switching message system utilized by NTT DoCoMo in Japan. PDC-P utilizes up to three 9.6Kb TDMA channels, for a total maximum bandwidth of 28.8Kb.

    GPRS:

    GPRS (General Packet Radio Service) is a specification for data transfer on TDMA and GSM networks.

    GPRS utilizes up to eight 9.05Kb or 13.4Kb TDMA timeslots, for a total bandwidth of 72.4Kb or 107.2Kb. GPRS supports both TCP/IP and X.25 communications.

    EDGE (Enhanced Data-Rates for GSM Evolution) enabled GSM networks are able to implement EGPRS (Enhanced General Packet Radio Service), an enhanced version of GPRS. EGPRS increases the bandwidth of each timeslot to 60Kb.

    Runtime errors 91, runtime error 53, runtime error ### … are you getting those annoying Runtime error message on your Windows 98 XP 2000 or Vista machine and want to know how to fix runtime error?

    Runtime error ### are some of the various types of runtime errors, the numbers might vary with each “Runtime Error” message but the root of all these problems is the same.

    Runtime Errors: Causes

    Most likely, Windows runtime errors are the result of some kind of glitch in the Windows registry because they originate in the registry. Every time you install or uninstall a program, a ’signature’ of that action gets registered in the Windows registry. Over time, with constant installing and removing programs - especially bad installs, your registry is getting bigger as well as corrupt entries. The more bloated your registry becomes, the more sluggish and unstable your PC becomes. And if not fixed, problems like runtime errors will arise.

    Runtime Errors: Fixes

    Some runtime problems are caused by specific software. For example, runtime error 53 or several others could arise due to a conflict between hardware and software. Check for any recent program installs or driver installs for your hardware - the Windows rollback feature for driver installs can be a boon to anyone looking for the root of the problem.

    However, fixing runtime errors manually can be annoying and time-consuming, one recommendation to fix all runtime errors safely and efficiently is to run a free scan of your computer to find out what the exact problem is and fix the specific runtime error instantly.

    Registry Convoy offers you a fast, efficient and safe solution to help get rid of runtime errors forever! It will scan your Windows registry and nuke those corrupt entries which are one of the most common causes of runtime errors. Why not taking the advantage of FREE SCAN of Registry Convoy to see if your registry has errors or mis-configuration and fix runtime error automatically?

    Common Runtime Error List

    Below is a list of the most common runtime errors which you will encounter on your PC:

    404 runtime error
    c++ runtime error
    runtime error 21
    runtime error r6025
    visual c++ runtime error
    runtime error 9
    runtime error 91
    runtime error 5
    runtime error 7
    runtime error 53
    runtime error 6 overflow

    As a freelance Linux consultant, many of my clients are often interested in making their VPS (Virtual Private Server) as responsive as possible. Since VPS servers by nature have somewhat limited system resources (often less than 1 GB of RAM), getting the best VPS performance can be a crucial part of running a successful server. To make matters worse, most clients assume that the VPS host has already optimized their server- which simply isn't true (even Rackspace, a wonderful VPS host, doesn't do this). Therefore, I've written this article as a brief introduction to some of the more common ways to get the best performance from a VPS.

    Tip #1: Disable system services
    The top way to increase your VPS performance is to disable any system services that are not necessary. Services that are never used will still use up valuable RAM and CPU time, and also possibly allow your server to be attacked remotely. If you don't need these services, why have them? Manage the startup scripts that start these services at boot time, and disable them.

    Tip #2: Configure MySQL properly.
    One of the more common ways to increase the available RAM (or to allocate more RAM to MySQL) is to configure the MySQL cache sizes. If your MySQL server instance is using too much memory, decrease the cache sizes. Likewise, if MySQL gets bogged down with large requests, increase the MySQL cache.

    Tip #3: Configure Apache properly.
    With Apache 2.0, many system administrators and clients alike have become confused as to the proper configuration of the Apache worker threads. Check how much memory Apache is using, and adjust the StartServers and MinSpareServers directives as needed to free up more memory.

    Tip #4: Clean up your modules!
    Without exception, there will always be modules or features that are enabled in memory hungry server software packages (such as Apache) that simply are not needed. Take a look at the configuration files for Apache, and decide if you need FrontPage support, or some of the other extra modules that ship with the VPS software packages. Disabling unnecessary modules or plugins will decrease the system memory that server software such as Apache requires, which will give you more resources for the software that needs it!

    Tip #5: Disable control panels.
    Let's face it, everyone loves the more popular control panels, such as Cpanel, Plesk, Webmin, and phpMyAdmin. Heck, I've even written tutorials on how to use some of these control panel software packages. However, disabling these software packages frees up quite a bit of resources- sometimes as much as 120 MB of RAM! Sometimes the best solution is to disable these control panels until you actually need them- then they can be turned on via a PHP script (albeit somewhat insecure), or via a command entered at a shell prompt.

    These 5 tips should decease the amount of RAM that your VPS uses by as much as 30-40%, which might save you quite a bit of money per month. Since most providers start out their VPS plans at systems with 256MB of RAM (and upgrades from there are expensive, often costing $40/month for an additional 256 MB), optimization of a VPS server is a crucial step. In addition, these 5 tips can be performed by a talented system administrator or consultant in typically less than two hours, which can mean a return on investment after only two or three billing cycles. What you do with the extra money saved is your business- you've earned it!
