coolwebsearch adware help please?

Hey ppl,
Avg has just picked up coolwebsearch, it hasn’t finished scanning yet but after reading up on the adware it seems like avg wont be able to remove it as its one of the worst to get rid of.
so i downloaded cwshredder and ran a scan, it came out clean?
I haven’t had any pop-ups, unknown bookmarks and my homepage hasn’t been changed at all.
Any help on what i should do would be appreciated thanks.

go to a site like Geekstogo or the bleeping computer or symantic most of these have a forum that tell you exactly how to get rid of these things or try trend micro. they havee a program called housecall its free but it takes a while it gets rid of most things
