neither is the case afaik. I have owned a fresh copy of norton since day 1 and run daily scans (never found a threat). I also run noscripts, adblock plus etc. I really don't think it's malware.
I have not configured anything in the start menu other than messing with file showing settings (show/hide hidden folders).
I am not overly concerned, as i'm hoping my upgrade to windows 7 corrects the problem when I get my copy. I was checking if anyone else had this issue or knew of a possibly fix.
have same problem if you find the answer please let us know.... Microsoft is crazy!
