Got 2 viruses and the AdwCleaner freezes  @20% during removal. Microsoft Security Essential and Malwarebytes does not detect these viruses.

No1: PUP.Optional.YahooChrome.     Registry[HKLM] SOFTWARE\Yahoo\SS

No2: PUP.Adware.Heuristic                C:\programData\{D19C2D22-6043-47E7-B400-83A351841204}

Haw, can I remove it?

Re: Adwcleaner freezes during removal of viruses.

There can be malware that prevents the full execution of Adwcleaner. Try using RKill and then doing a full scan with the new version that Coco has suggested.
