E-mail viruses double in 2002

E-mail viruses are now twice as prevalent as they were in 2001, with one e-mail in every 200 containing a virus. Virus-scanning company MessageLabs said it stopped 9.3 million viruses in 2 billion e-mails this year, which equated to one virus in every 215 e-mails. That compares with 1.8 million viruses stopped in 718 million e-mails in 2001, or one virus in every 398 e-mails.

According to the company, which measured results up to the end of the second week of December, the most active virus this year was Klez.H, with 4.9 million copies stopped by MessageLabs. Yaha.E came second with 1.1 million copies, then it was Bugbear.A with 842,333, Klez.E with 380,937 and SirCam.A with 309,832. These figures represent only the numbers stopped by MessageLabs for its corporate customers. The actual numbers of these viruses are much higher.

Although Klez was the most active virus, Bugbear was the most dramatic outbreak of the year, infecting one in every 87 e-mails at its height in October. Its dual-mode attack saw it accounting for 30 percent of all reports of viruses to antivirus company Sophos in the last month--well ahead of former top-spot incumbent Klez, which by then only accounted for around 8 percent of all reports.

Klez could reach only one in every 169 even at its peak, while Yaha never rose above one every 268, said MessageLabs. The two most dramatic outbreaks of all time recorded by MessageLabs remain Goner, at one in 30 last December, and the No. 1 LoveBug, which hit one in every 28 in May 2000.
