OK, well due to getting infected by adware (thanks to the 800-something KB file) and a hell of a lot of crap through Limewire, I decided to uninstall it not to cause further damage until I got my computer fixed. Then I wanted to get one last song, so I downloaded Limewire again, got the song and uninstalled it. Now the problem is, it keeps trying to start up even though the program isn't on my computer. This Java error thingy comes up, telling me to send a report to bugs@limewire.com. I close it, but it keeps going on! What can I do??

Sounds like you have a virus.
Always make sure that you're using a good AV program. Keep it updated & scan all downloaded files before opening!!
