I just ran Avast Custom scan made by myself, because I was redirected to some ad sites, which WebRep ranked yellow and red. But I noticed, that the scan is a lot faster, than with the previous version, although it’s the same custom scan and I have even more files on my computer, than on the last time. Has the Avast developers made the scan faster in the new version, or do I have some kind of problem?
If you have a lot of videos files, they recently changed the engine so it basically ignores them.
If you are having re-directs, you might want to have a look at the virus & worms section, quite the little outbreak they are dealing with.
