i used to use limewire, and thats how i got viruses on my computer the first time you guys helped me out, i was desperate to find that old game: Abe's Exoddus. And so i scoured the internet looking for a download more than just a demo, and a link opened up limewire (which i had been using previously) which started downloading the file, i waited and waited as it was a few gigs of space, luckily the second i couldnt get it to work i deleted it to stop any further malware, then, upon finding out i HAD malware already offloaded i got rid of LW.
Moral of the story, sometimes it's best not to take chances, even if the reward looks worth it.
