    You can manually run the Malicious Software Removal Tool, follow the steps below :
    • Go to Start >> select Run >> type MRT >> press Enter.
    • A screen will be displayed, click on Next button.
    • The removal tool usually runs the Quick Scan, but for more thorough results, choose Full Scan >> click Next
    • The Malicious Software Removal Tool will scan your entire hard drive for infections and problems.
    • If you click on the View Detailed Results of the Scan option on the Results page, you should see which viruses, worms, and trojans the removal tool scanned for and if an infection was found.
    • Click Finish on the Scan Results page to exit the Microsoft Malicious Software Removal Tool

    Where Malicious Software Removal Tool (MRT) is located ?
    MRT is located in WINDOWS\system32 and is named as MRT.EXE. You can check for MRT at this location.

    Then, from Start -- Run -- copy and paste "mrt" (without quotes) into the command line and click OK.
    Wait for a while. After sometime, the tool should open. Click the Next button.
    Put a mark next to 'Full Scan' -- click Next and perform a Full Scan
