LimeWire pop-up problems... HELP!
 

Hello. I'm new here. You see, I have a problem. I just downloaded a game for iPod it's a .zip folder. And then I extract it and open the folder. And file that says 'Setup' is there so I open it. It's really stupid of me to try and open it. A warning pops-up says 'We cannot open your file', I think. And then I open LimeWire. I canceled all my downloads and exit LimeWire, literally. Then the .cmd appeared; of course I exited it. And then an Internet Explorer appeared. I uninstall LimeWire quickly.

After the uninstalling a pop-up again appeared. But it has a Java sign on it and it says 'One or more necessary files appear to be invalid. This is generally caused by corrupted installation. Please try downloading and installing LimeWire again. If the problem persists, please visit www.limewire.com and click the 'Support' link. Thank you.' I don't really, completely understand what it says but I download the setup. Afterwards I downloaded the software and then I tried to ignore the Warnings. And then a warning again pop-out saying that it cannot be completed. So that's it.

Can you please help me. I don't know what's really happening. Please help!!!

You sound like you downloaded a virus in that zip file...I'd suggest you forget about limewire for the moment and do a complete system scan with your AV..
If that scan comes up with nothing and actually even if it does you should do a Highjack this log and go to one of these sites and have it checked...
