Limewire keeps popping up when I don't click it.
 

It's like, every five seconds. And I can't re download it because of these three things:
1. All my songs will be deleted off my iTunes
2. A sign will come up in place of Limewire saying "A necessary document is required to start" or something of the like, and it comes up every 5 seconds or so.
3. I already tried re-downloading it, it STILL opens every 5 seconds.
While typing this, Limewire has come up 18 times. How can I stop this? Also, ever since this started, CTRL+ALT+DEL don't work, so I have a feeling Limewire is tampering with my computer.
How do I fix this NOW?:bangh:

First off ... Your probably Infected. Reason for the continual Opening.
Try this.

AVG(free) might be able to fix it. Be sure to update it before you scan your computer: AVG Free Advisor: AVG Anti-Virus Free, then follow the prompts.
Once AVG has fixed the Problem you can delete it if you want to.

If AVG doesn't fix the Infection problem, then Try this.
