I got this free program called cyberdefender, and, although I had Norton, I wasn't getting the definitions updated. This cyberdefender program updates its definitions every time it scans, and it helps block spyware, viruses, scams, etc. It only has little unobtrusive ads in the top (that's how it's free). But now the worm is gone, and I can use limewire again!!! I swear to god this is not fake!! I thought it was fake at first too, but it works, and really helps.
