New email virus disguises itself as IE7 beta?
A new virus has been released into the wild and is showing up in inboxes disguised as an IE7 update. Rather than showing up as an attachment, it is an embedded link in a Microsoft-ish image. The true nature of the virus has not yet been fully explained.
The file is actually a new virus called Virus.Win32.Grum.A, and security experts were still analyzing it Friday to see what it does. Sophos PLC said it can spread by e-mailing itself to contacts in a user's address book. The virus tampers with registry files to ensure it gets installed, and it tries to download additional files from the Internet, said Graham Cluley, a senior technology consultant for Sophos.
