If you receive an e-mail offering a download of Internet Explorer 7 Beta 2, delete it. A new virus is spreading all over the web. The e-mail includes a convincing graphic that looks like it could really be from Microsoft, and the virus is delivered when recipients click on the included link. The e-mails carry the subject line "Internet Explorer 7 Downloads" and appear to come from admin@microsoft.com. They include a blue, Microsoft-style graphic offering a download of IE 7 beta 2. Clicking the graphic will download an executable file called IE 7.exe. The file is actually a new virus called Virus.Win32.Grum. Security experts are still trying to analyze the virus, which may affect your registry, mail contact list or steal personal information from your computer.
