A history of computer viruses

The next segment in the report is on how to combat computer viruses with the development of anti-virus applications.

The current status of microcomputer viruses will also be discussed, naming the most common types of viruses and the most harmful type at this present point in time.

Details of the most recent outbreaks of computer viruses, such as the “Melissa”, “I Love You” and the most recent “Anna Kournikova” viruses will be explained, and why they are so harmful.

I will also give you my recommendations on how to combat this threat of computer viruses, what Anti-virus Applications that I believe should be used, and why updating your virus definitions for these programs on a regular basis is so vital and important in your quest to have a happy and uninfected computer.

And finally, I give you my conclusion in which I can only hope that you will find helpful.

A History Of Computer Viruses

. . .
The virus was spread by making unlimited copies of itself and infecting computers over a large network. It’s virus definitions are updated daily, and a full working version with a thirty day evaluation license can be downloaded from “www.

The Current Status Of Microcomputer Viruses

The main types “Boot”, “Program” and “Multi-partite” (a combination of both boot and program) viruses are all still a threat to anyone who shares files from other computers, or who is connected to the Internet or a network.

In the 1950’s at Bell Laboratories, “John von Neumann’s” theory in which he made in 1949 was put to the test. The first algorithm contains the actual virus variants, and the second is the algorithm that complicates the viruses tracing.

The first “Polymorphic” viruses appeared in 1990 “Chameleon”. In 1999 the “Melissa” virus was in the wild and replicated under “MS Office 97” and “MS Office 2000”, using the e-mail program “MS Outlook” to spread.

Evil and conniving programmers have found another use for the macro, and that is to turn it into a “Virus” by making a number of operations that can Reich havoc on your computer. As of 1995 when the first “Macro” viruses were introduced, programmers had to change the way their companies’ anti-virus programs scanned for viruses as a new technique had to be used to find these viruses, otherwise the viruses would go undetected. This virus infects Word documents by changing the data format, and if the virus is run under “MS Office 2000”, it has an extra action that disables “MS Office 2000” anti-virus security, which can make it go undetected. First of all, there were two versions of the virus “Cascade”, followed by the “Vacsina” and “Yankee” viruses, then “Vienna”, “Eddie”, and then “PingPong”. This pyramid of addresses from peoples’ address books is the reason why macro viruses made for legitimate e-mail programs such as “Microsoft Outlook Express” spread to so many computers and so quickly in just a short period of time.

The most recent outbreak was in February 2001, the “Anna Kournikova” virus, which is another virus sent as an attachment via the e-mail in “MS Outlook”.
