Computer Viruses

 

Computer Viruses are pieces of programming code which have been purposely written to inflict an unexpected result upon an innocent victim. There are now approximately 50,000 viruses and their variants for which known cures of 'vaccines' are available.

Viruses are transmitted within other (seemingly) legitimate files or programs, the opening, or execution of which, causes the virus to run and to replicate itself within your computer system, as well as performing some sort of action. Such actions can be as harmless as causing characters to 'fall off' the screen (early DOS based Virus in the 1980s), to the most malicious viruses which destroy data files and replicate themselves to everyone in your e-mail directory.

It is essential to guard against virus attacks by a combination of cautious, guarded, awareness, together with a modern anti-virus package and regular updates - every two weeks is recommended.

There are many Internet sites providing updates on Viruses; here are some examples www.sophos.com or www.symantec/avcenter.
