Unknown Downloads
 

I have the latest version of Limewire PRO, and for some reason, every so often, I'll start it up to discover hundreds of downloads in the "Complete" folder have taken place for various different .zip files. I have no idea where these downloads are coming from, each file is about 851.7 KB and they take up hundreds of MB of space on my hard drive. I'm getting sick of deleting them. Where are these coming from and how can I prevent these files from getting onto my computer?

It's a virus! Don't open it! See LimeWire continually Popping up every few seconds & also Opening at System Startup
