"With millions of junk e-mails from the first strain of the e-mail worm still crossing the Internet, virus hunters Wednesday discovered a new variant, Mydoom.b, that reportedly targets software giant Microsoft's Web site. If opened, Mydoom.b also blocks access to several common anti-virus sites, an attempt to make the virus more difficult to remove," reports The Mercury News.
Microsoft has also followed SCO, the original target, in offering a $250,000 reward "to anyone who helps authorities find and prosecute the author", adds AP.
