Click on the start menu. Then select Run. Under this prompt write 'msconfig' without quotes. Then under Startup tab click on the button "Disable all". Then press Apply button. Again under the Services tab Check the option named "Hide all Microsoft services". Then click on the "Disable all" button. Again apply and then press ok. Restart the machine and perform a full system scan with the antivirus software installed. Follow the instructions mentioned by the antivirus software. This will solve your problem provided that the virus definition of your antivirus is uptodate.
