This is the latest in a series of monthly charts counting down
the ten most frequently occurring viruses as compiled by Sophos, a
world leader in corporate anti-virus protection.
For August 2001, the chart is as follows, with the most
frequently occurring virus at number one:
"The Sircam
worm has now topped the charts for two months. The Magistr worm, which has
dominated the charts for half a year, is continuing to make its
presence felt in second place," said Graham Cluley, senior
technology consultant for Sophos Anti-Virus. "Both worms play a
similar trick - neither of the viruses use a standard filename or
subject line so it is harder for users to know what to look out
for. Careless clicking can lead to catastrophe - keep your
anti-virus software up to date and do not open unsolicited
attachments."
1051 new viruses were discovered and protected against by Sophos
Anti-Virus during August 2001.
The total number of viruses Sophos now detects and protects
against is 67221.
