Hi -- I got avast virus alerts when visiting several microsoft web pages. The pages are:
http: //www.microsoft.com/windowsxp/using/setup/tips/advanced/ntfs.mspx
and
http: //www.microsoft.com/windowsxp/using/setup/maintain/backupfiles.mspx
(I have added spaces, so that the links are not clickable)
I get a msg something like this:
Virus detected. Malware stopped before it could enter your computer. Click "abort connection" and the download of the dangerous file will be cancelled.
File name:
http://rad.microsoft.com/ADSAdClient31.dll?GetAd=PPG=consDLQ [I think]
Malware name: VBS: Zulu
Malware type: virus/worm
VPS version: 06 40-4, 10/06/2006
I am using Firefox 1.5.0.3 with the NoScript extension.
What's weird -- beside the fact that I am getting this warning on MS pages, which ought to be clean -- is that I visited these same pages about a week ago, and did NOT receive any alert. Then I bookmarked these pages, or actually, added them to the Mozilla link bar (or whatever it's called). When I revisited them, I got the alerts. (But sometimes, I can go to the page without triggering an alert -- but usually I do get it.)
I am wondering if this is some kind of a false alarm. I thought maybe it had something to do with some advertisement on the pages -- but there are no visible ads on the pages.
Can anybody explain this/ reassure me?
Is my computer really still at risk of drive-by downloads, even using FF and NoScript?
