there is another prog called "hijack this", you can likely just google to find it. I believe this one may be a bit better than sypbot, least thats what i have heard.
Hijack this is a "no install" prog, you just click on it and it opens, you click on scan and it scans your puter for adware, spyware, and other garbage. YOu do have to be a bit careful as it scans all processes, some that you do want running.
But, you can check the results of hijack this and look for those files that you mentioned.
You can also just cut and paste the results to a post here and we can help you with what you should remove.
I have used hijack this a few times and its helped me out.
By the way, how did you come up with just these file names?
