who recommended spyhunter? http://en.wikipedia.org/wiki/SpyHunter
It seems to be legit, but it's crap software according to reviews it's slow, doesn't work all that well, doesn't pick up more obvious spyware. Basically it's a waste. Use hijack this, spybot search and destroy. Hijack this is the best, along with something like Procmon - you can get rid of just about anything.
