Here's what you can do to find any viruses or other malware on your computer: Download Autoruns (http://technet.microsoft.com/en-us/sysinternals/bb963902.aspx
) This program will detect all files that are configured to run during system boot up, including malware. Once you've downloaded the program, restart windows in safe mode, so that any viruses you may have will not be able to run. Once in safe mode, open Autoruns. You'll still see all programs configured to run upon start up, even though most of them were not allowed to. When Autoruns is open, click the "Options" tab, "Filter options", and make sure all boxes are checked. This will filter out most programs that came default with the computer. Now, look over the list of programs found for anything that seems unsafe or suspicious. Anything not verified or unknown will be highlighted in red. Right click these files and left click "Search online" to find info on these files, and delete them according to what you find. Since any viruses were not allowed to run in safe mode, they won't be able to duplicate themselves once deleted, so they should be gone. If this doesn't work, trying a virus scanner might work.
