It closes the moment I try to run it.
I tried to run... the smartkiller thing to see if that would work.
But the only link I keep finding to download it from leads me to a progam that also errors telling me that it cannot find CoolWWWSearch.SmartKiller (v1/v2) on my system.
That is not an error. Its telling you it can't find it. Right. So something is keeping you from running hijack this. Either you have to keep throwing scanners at it or start from scratch. Have a look at this tutorial for a good list of scanners and detailed instructions. If you choose this route, follow them carefully. Check out Itty Bitty Process manager in particular.

Good luck.
