Sobig.f is programmed to stop sending itself today. For those plagued with hundreds or thousands of the Sobig email flooding their inboxes, this will be a tremendous relief. But what of other worms that don't self-destruct? The Klez.H worm is well over a year old and still topping prevalency lists. A few days ago, I received a copy of three year-old Hybris. Are these worms that tenacious or are users just that lax about using protection? The answer may depend on the virus. Certainly Klez.H has a few tricks up its sleeves that can make detection and removal difficult. But Sobig.f, Hybris, and most of the other circulating threats do not. Worms like these seem to survive purely on dumb luck, striking pay dirt on unprotected systems. Online scanners are always up to date and offer a quick, easy, and free method of checking your system for viruses. Have you had your scan today?
