Restart the computer, and the instant the desktop shows up (before all the icons in the tray appear), hit ctrl+alt+del and close the application "cloud av" (or cloud something I'm not sure) right away (if you have a gazillion things running like my computer you'll want to click the name tab to sort them alphabetically and find cloud quicker). Once it's closed, I did a search for files/folders named cloud and deleted everything related to the virus (some was in windows/system32, some was in startup, and I think some may have been elsewhere). Finally, I ran my antivirus software, though it didn't find anything at that point.
Hope you're able to fix your comp... all the f'ers that make these viruses should be shot
