January Evil Top Ten from BitDefender

First off, the much-talked-about MyDoom virus has managed to eke into our monthly top 10 – not an easy achievement, considering that it has been released just a few days ago (on the 26th of January, to be more precise). Not only that, but this nasty critter has managed to show up on our radar one million (that is right, 10^6) times over a period of 24 hours. That says something about how well some people have internalized last year’s lessons, doesn’t it? Actually, at the top of our top sits a virus which makes a good textbook case of widespread (and distributed) negligence. It’s been months since it was first released, but hey, who’s to say it’s antiquated? We’ve released a sig update and a free cleanup tool within the first few hours, the people at Microsoft have taken some of their precious time to release a cleanup tool of their own, but… Ladies, gentlemen and other good folk, this month’s highest spreading virus is, well, like it or not, Msblast.A; it seems to be heading swiftly for a dishonorable mention in the virus hall of shame, there to lie along such olden goldies as the Morris worm and the Brain virus. The entire top ten for this month looks like this:

Virus Name	Infected systems
Win32.Msblast.A	18.58%
Backdoor.Agobot.3.Gen	17.03%
Win32.Parite.B	12.96%
Backdoor.SDBot.gen	10.87%
Trojan.Downloader.Dyfuca.J	8.78%
Trojan.Downloader.Dyfuca.V	8.12%
Win32.Msblast.B	7.82%
Win32.HLLP.Hanta.A	5.66%
Win32.Msblast.F	5.16%
Win32.Mydoom.A@mm	4.96%

Based on past experiences, and the emergence of MyDoom B, which has yet to make the rounds, we strongly suspect that next month will see a peak of activity on the virus front, but until then BitDefender prefers to keep users interested and perfectly protected. This report, called the "Evil Top Ten", is based on the number of virus occurrences confirmed through BitDefender Response Team tracking. Note: BitDefender users were protected since the very beginning against the threats described above. Moreover, BitDefender experts were among the first to release antidote tools, freely available on the Internet. Commercial versions of BitDefender start from USD 29.99 and are available for 30-days free evaluation from the BitDefender websites or local distributors.
