Well I went through all the earlier instructions but I couldn't find any files that were taking up my cpu usage other then the system one. I have the same problems though, Limewire keeps popping up and I can't use task manager by using ctrl + alt + delete. I've went through all these instructions but I can not find a virus or file that is doing this. This is just getting pretty annoying and frustrating. So if anyone has any idea please message me asap or send me an email. It will be greatly appreciated. Thanks.
