No prob
Run your AV program. Programs like Spybot & Ad-Aware (they're in the thread I gave you) will be really good as well. Ad-Aware's pretty good at getting rid of Trojans.
If you can't clean up your system, follow the links in that thread & go see Norbiesworld (link in the thread).
Watch what you download & scan a file before you open it!
Good luck
