Alright, I uninstalled Limewire because I noticed two things happening:

1: It kept popping up, even when I shut it off
2: My shared folder had anywhere from 50-400 things that I DID NOT DOWNLOAD AT ALL. I found the root of the installations going to:

C:\Users\(my user name)\-\


I did the thing with BFU to try and rid of it, but it did not work. My virus program (Norton) isn't picking anything up.

I've decided to keep LW off my computer until I fix this.

Now, a pop up keeps coming up every minute or so saying exactly this:

One or more necessary files appear to be invalid. This is gernerally caused by a currupted installation. Please try downloading and installing LimeWire again. If this problem persists, please visit Lime Wire » Official Website & Free Download, BitTorrent « and click the 'Support' link.
Thanks you.

STARTUP ERROR!

To tell you the truth guys, I have no idea what to do. After all of this is fixed, I wont be coming back to Limewire. The fact that there isn't much protection from the files shared scares me to the point of not wanting to use it anymore.

PLEASE HELP THOUGH
