I think running the "hijackthis" utility would be a start.
The thing is if you can not get to the Internet to download it it might be tough. I could email you a copy - or - since you are posting here you have access to the Internet somehow to download it. Just google for hijackthis.
If you are not comfortable with running the utility you might want to get a professional or geek type neighbor to do it.
If you have any particular questions post here
Run hijackthis
Then do a scan and look through the list of items and select what to get rid of.
