Sophos Press Release

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 March 2002, the chart is as follows, with the most frequently occurring virus at number one:

"Despite the appearance of new viruses like Bound and Caricature, it's Klez and Badtrans that have snatched the top slots this month," said Graham Cluley, senior technology consultant at Sophos Anti-Virus. "This demonstrates that it isn't just the newer viruses with higher profiles that users should be looking out for. Just because a virus isn't hitting the headlines doesn't mean it isn't continuing to cause problems."

The Caricature (W32/Caric-A) and Bound (W32/FBound-C) email worms, both of which emerged during March, attempt to play further confidence tricks on computer users. Caricature poses as a screensaver of Bill Clinton and Bound masquerades as a security patch. Once again, both of these worms can be protected against with anti-virus software and safe computing practices.

510 new viruses were discovered and protected against by Sophos Anti-Virus during March 2002.

The total number of viruses Sophos now detects and protects against is 73,079.
