Avast keeps blocking repeated attempts to access malicious sites

I have seen several similar threads. Something keeps trying to access wvydeo, sindelclick, xmlka, and movieroomreviews. Browser (IE and Chrome in use) does not have to be open to get message. Is this an “idle crawler”? Ran MBAM (nothing found), Tweaknow reg cleaner (removed 5 values pointing to nothing), Spybot was so dogged down it was unusable. Cursor is slow/jerky, page loads take forever.

I tried to download FRST from bleepingcomputers, Avast blocked it as malware! How do I proceed from here?

I am sending this from a separate laptop, the infected unit is so slow I can’t seem to send the post.

I miss the days when I could just do a fresh install to eliminate these problem.

Any help is of course appreciated.

For the FRST alert temporarily disable webshield, this is a new version and as such always ticks webshield off
