"The MyParty worm duped computer users by pretending to be a link to a website containing snaps of groovy partygoers. But not everything that ends in dot com is a web address, it can also be an executable file," said Graham Cluley, senior technology consultant for Sophos Anti-Virus. "It was a simple psychological trick and many people fell for it. The message is simple: stop double-clicking on unsolicited email attachments, even if they appear to come from someone you know."

February also saw the emergence of Coolnow - a worm that infected users of MSN Messenger. Although it did not break into the top ten, Coolnow continues to infect PCs and therefore offers a reminder that virus writers are constantly using new platforms to spread their malicious code.

739 new viruses were discovered and protected against by Sophos Anti-Virus during February 2002.

The total number of viruses Sophos now detects and protects against is 72,569.
