A new worm was spammed out this weekend purporting to be a beta version of Microsoft's Internet Explorer 7 browser.
Emails with spoofed headers such as admin@microsoft.com contain a file that claims to be a beta version of the browser, despite the fact that the full code was released in October 2006. The 'ie7.0.exe' file contains the Grum-A worm. Vnunet has more.
