KELLNER: Avoiding high-priced anti-virus scam

A reader in Chantilly received a bit of a shock about three weeks ago, and then got what nearly became a very expensive online education. One of the latest scams, or rip-offs if you prefer, to hit computer users via the Internet is an “anti-virus” scam, where slick operators promise to fix your computer online, and maintain it for two years, all for the “low” price of just under $270.

The reader, who asked that his name not be used, was charged just one cent under that figure, $269.99 to be precise. Given that good anti-virus software for Windows-based PCs can be had for as little as $8.99 at Amazon.com and generally for not more than $40, the price this reader was charged ranged between roughly seven and 30 times what they should have paid.

The incident started innocently enough: the reader was ending a Windows work session, and the program indicated there were updates to download. The reader let this go on overnight, returning to the computer the next morning. On firing up Internet Explorer, Microsoft Corp.’s popular Web browser, the reader noticed something was different.

“I noticed that the address bar and the other tool bars at the top would go away when the arrow was moved away from the top, thus making the screen slightly larger,” the Chantilly reader later wrote. “This started becoming very annoying after awhile, particularly, because some of the material was not coming back. And it was time consuming.”

The reader then called “a number I thought was [Microsoft Corp.‘s] tech support,” which he said was obtained via a Google search.

He added, “They talked me into letting them on my computer. They brought up a page that said I had over 56,000 error messages and that told them that my computer was in terrible shape and even if I bought a new computer, the same mess would come through my Internet service and infect a new computer.”

How to Get The Best Antivirus Support

Computers have effectively changed our lifestyle but they are always prone of virus intrusion. As their importance is increasing a proper protection for them is also required. A virus can intrude into a computer through any data storage device which carries infected data and comes in contact with the system. If a computer is connected to a network, chances of virus intrusion become very high if it is not protected by effective antivirus software. The Internet has changed the whole method of communication and now the world seems as an area without boundaries. In this scenario chances of virus intrusion in a computer connected with the Internet have become very high.

What is a computer virus?

A computer virus is not like of a virus which infects a human body. A computer virus is a program that can copy itself and infect a computer. A computer virus is also called malicious software or malware. There are many kinds of malware also that can not reproduce themselves but can infect the computer. If files on a network file system get infected by computer virus, chances of spreading of virus will become very high because that file system is accessed by other computers too.

What is Antivirus software?

Antivirus software is a program that can detect and eliminate viruses on a computer. A virus removal software application uses two common methods to detect viruses. One method is of using a list of virus signature definitions. In this method the contents of computer's memory (RAM and boot sector), files stored on removable or fixed drives (floppy drives, hard drives) are examined, and then compared with files against the database of known virus signatures. This method gives protection to the computer against only those viruses whose virus signatures are stored in the database.

The second method is based on heuristic algorithm to find out viruses based on common behaviors. This method is more effective as it can detect those novel viruses that antivirus security vendors have yet to create a signature for.

A user can download and install computer security software from the Internet for protecting his system. There are many vendors who provide solution against different kinds of security threats from computer viruses. Some names like Avast, McAfee, Norton and Kaspersky are very common in virus removal software.

Although it is very easy to download and install antivirus program but it must be done under an expert's guidance. There are several things that need to be checked before installing this type of software on a computer. First of all, make sure that your computer is not infected by any kind of virus. Virus removal software might not work on a computer that is already infected by viruses. Some type of computer viruses mimics the behavior of different files; antivirus software may not be able to detect them.
