I use Firefox 99% of the time, but tonight I decided to update IE 6 to the brand-new IE 7. So I opened Firefox, went to Microsoft.com, clicked the update button for IE on their homepage, and .... absolutely nothing happened. I guess they block FF. Not surprising, but no big deal. Instead I opened IE 6.x, again went to Microsoft.com, clicked the same update button, and .... my anti-virus scanner (Alwil Software' Avast, which I highly recommend) immediately popped up! It read the Microsoft download as a virus and it urged me to abort the connection. I rebooted and tried it again with the same results. It cites "VBS: zulu" as the culprit.
