AVG PC tuneup

so guys here is the problem…I’ve removed program with AVG PC tuneup(force remove) before I have unistalled it.So It is still there and I can run it,but can’t unistall it anymore because I can’t find it with CCleaner or Add/Remove programs..
Any idea how to unistall it?
thanks
Answer #1
Search finds it only in Windows/Prefetch…does it mean it is completly cleaned ?
Answer #2
delete from registry .
