Sircam virus leads 2001's list of infections

The Sircam virus affecting 32-bit Microsoft Windows systems topped the 2001 list of worst viruses compiled by Panda Software Inc. of Glendale, Calif. W32/Sircam accounted for more than 24 percent of reported infections.

At the bottom of the list were the Nimda worms, versions A and D, which appeared late last year but managed to cause more than 8 percent of infections reported to Panda's technical support service. The longest-lived virus was Hybris, which has ranked on every monthly list since its appearance in late 2000.

The patterns of infection suggested two trends, Panda officials said. Explosive viruses such as Badtrans and Nimda peaked and, after doing considerable damage, disappeared. Slower codes such as Hybris kept a lower profile but refused to go away.
The complete list:

W32/Sircam'24.2 percent; W32/Disemboweler'18.1 percent; W32/MTX'12.5 percent; W32/Hybris'9.4 percent; VBS/Help (Happytime)'8.3 percent; W32/Magistr.B@mm'8.1 percent; W32/Navidad.B'5.6 percent; W32/Badtrans.B'5.1 percent; W32/Nimda.A'5.1 percent; and W32/Minda.D'3.3 percent.
