Others 29.8%

“June’s virus chart is topped by the highly destructive Magistr worm. This worm has been dominating the top ten for the last three months. It seems that the simple message – don’t open unsolicited attachments – has not yet hammered home,” said Peter Cooper, UK support manager, Sophos Anti-Virus. “What’s more, the highly publicised Homepage virus is also continuing to infect many people. It seems computer users are still ignoring warnings and have neglected to update their anti-virus protection.

June also saw the resurgence of the Apology virus which prevents infected users from reaching the websites of many anti-virus vendors, thus preventing them downloading protection. Sophos reminds that users who regularly update their anti-virus software will be protected from all known viruses.

794 new viruses were discovered and protected against by Sophos Anti-Virus during June 2001.

The total number of viruses Sophos now detects and protects against is 64,894
