I have this problem recently which involves resurrecting ad window. When I check my task manager, under Applications it says VerAds and ads4.exe under Processes. I googled them both and discovered they are related to each other according to this.
I already tried scanning with MSE, MBAM, HJT, Eset Online Scanner and SUPERAntiSpyware. None of them removed this for me. I most likely need professional help with this.
EDIT: Ran OTL and found out where all the files were kept. Killed the process and deleted C:\WINDOWS\system32\ads4.exe.
