Scan your Windows Computer with Windows Tools

You can scan your computer for free and without the use of any extra antivirus software by running the Microsoft Windows Malicious Software Removal Tool. All you require is access to the run panel and be able to run tasks. Firstly, open run (start->run) Then type in mrt. You should see a new window appear. Read it over and make sure the month and year are current (if they are not-update Windows). Then you can do a full or quick scan. The scan takes around an hour for full, and 5-10 minutes for quick.
