If your computer is not running as well as usual or you are receiving constant pop ups from Chrome.exe, there is a good chance you have a computer infection. Immediate removal is necessary to restore your computer to working order. You can remove viruses and other threats from your computer using the free Security Essentials anti-virus and anti-spyware application provided by Microsoft.
Open the Windows Start menu and select "Programs" and "Microsoft Security Essentials." If the anti-virus application is not on your computer already, download and install it from Microsoft (see Resources).
Click "Full Scan" and "Scan Now."
Click "Remove All" once the virus scan completes to remove the found threats from your computer.
