Ag!

Ok so I have a really piece of crap toolbar that somehow showed up on firefox, I think its for my old spyware firewall $250 a year program that I deleted and the ■■■■ toolbar is still there, its even on my fancy new IE7 (don’t ask) I also have a .exe file on my desktop that just wont delete im geussing its for a game because its called “Rappelz.exe” and my brother has a game called that installed on his computer, it would not bother me if it was in another folder but it can’t be moved ether a error comes up saying its being used, I check in the task manager to see if its runing and its not, I even made sure it was not write protected, nothing! When I try to run it it does nothing ether no error just nothing, can anyone help me out?
