Security experts reported no widespread damage Friday morning, but they said the virus is notable for a couple of reasons.
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 a link rather than in an attachment, which makes it harder to stop it from reaching in-boxes.
"The idea of sending a link seems to be a trend among attackers; it's still fairly new and it works much better than sending a file," said Mikko Hypponen, chief research officer at F-Secure.
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.
