MyDoom Gets Nasty

MyDoom.F spread last week, and, unlike other variants of the persistent worm, it could cause damage by randomly deleting files, including Microsoft Word and Excel documents on infected computers. MyDoom.f arrives as an attachment to E-mail messages under a large number of subject lines, including "Read this," "Your order is being processed," and "Bug." It installs malicious code that, among other things, conducts denial-of-service attacks against Microsoft.com and RIAA.com, the Recording Industry Association of America's site.
