Sophos, a world leader in corporate anti-virus protection.
For December 2002, the virus chart is as follows, with the most

"Two worms account for over a quarter of all support queries we
receive at Sophos. Klez, the biggest virus of 2002, and Bugbear

December, the total number it now protects against is 79,017.
