My point was that the same false positive can show up five times in various System Restores (try putting UBCD4 on an .iso for a similar experience, and some of the anti-virus scans only include folders, not exclude ! ). And you may end up having to edumacate your various scans again and again.
My apologies for the unclarity. Note, I agree that System Restore can be a big help to some of the people some of the time, for me it is a close call what to do. The 15% stuff is weird tho.
btw, sometimes I see Experts Exchange get ripped (e.g Web of Trust gives them a mediocre rating). Yet, I found that a lot of times they deal with techie issues quite well and that they can be a good resource properly used. Somehow I tend to see the answers, even without bypasses, maybe it they have a mixed policy.
