News: Sobig lingers despite shutdown date:
"Sobig is still rampaging around the Internet, two months after the virus was supposed to have terminated itself. "

E-mail security firm MessageLabs said Friday that Sobig was the third most active virus in November, with some 264,000 copies being detected by its e-mail virus-scanning servers.

Although this activity is well below the virus's peak, it is still surprising as Sobig--like several other members of the Sobig family--contained a built-in shutdown date that was supposed to prevent it propagating after Sept. 10. Sobig.F's continued proliferation is due to a combination of factors, including the successful efforts that prevented it wreaking even more havoc and the fact that many PCs are set to the wrong date, according to MessageLabs.
