I do believe I was infected with that, I used CWShredder, if memory serves me correctly it didn't fully sort the issue. It is a safe program though (from my experience). You'll also find a number of spyware programs listed in
this thread (including CWShredder), they might help.
A little more technical, but I really like
Bazooka . It scans quickly and, for me, has detected 2-3 spyware that ad-aware/spybot have never detected. Instead of removing it for you though, you need to follow online instructions to get rid of it. But it has helped me a couple of times with extremely annoying spyware.
