Clamwin is reporting chrome.dll: W32.Virut.Gen.D-148 and chrome.7z: W32.Virut.Gen.D-148 as virus' when they are not. Please see this link as it seems these two files keep going in and out. I monitor several PCs and find it way to frustrating to go in and filter this false positive out on every PC. But I get a report from each of PC that it has this virus which is quite annoying. It seems that the database admins for Clamwin are making an effort to fix this, but it still keeps appearing almost daily.
