A new worm is spreading on the internet which advertises itself as Internet Explorer 7 in beta version.

The Register reports that this worm may come from emails which has a sender name called admin@microsoft.com and the subject is “Internet Explorer 7 Downloads.” The file that is attached on the message is ie7.0.exe and the worm that infected this file is called Grum-A worm. The beta 2 version of IE7 was released by Microsoft a year ago.

This was not the first time that a worm disguised itself as a file which is affiliated with Microsoft. A worm in 2003 posed as an update and it fooled many users. There was a case where hackers directed surfers to a bogus Microsoft website.
