Worm: Scan your PC today

A "protection scan" at the Windows Live Safety Center before tomorrow would be a good idea for all family PC owners. "A computer worm that infiltrated hundreds of thousands of computers last month is expected to awaken tomorrow, destroying documents and files on infected machines," reports Washington Post security writer Brian Krebs. Word, Excel, PowerPoint, and Adobe pdf files are in jeopardy. The vast majority of the some 300,000 infected Windows PCs are outside the US, but "at least 15,000 computers" US PCs are infected, and "home users are going to be the hardest hit," according to the Post.
