i once had a hacked version of limewire and my computer got filled with viruses but after i knew about that i formatted my pc and got an anti-virus. and i downloaded limewire from www.limewire.com. and i noticed after a week that my pc is going slow and like very slow in processing. is it the cause of limewire because my pc is deserted and has nothing but a video and audio player, anti-virus, anti-spyware and limewire and nothing else.??is that the cause of limewire ??
