How to Scan and Fix a Virus for Free

If your computer is infected with a virus, you can remove it from your computer without paying any money if you use software that is free for home users. This software scans your computer for viruses and removes any that are found, making your computer safe and secure again.

Step

Download a virus-removal tool (such as Malwarebytes, Spybot Search & Destroy or Microsoft's Malicious Software Removal Tool) from the web by visiting its home page and downloading it (see Resources).

Step

Run the installation file you downloaded and install the software on your computer. Once the installation finishes, restart your computer.

Step

Press the "F8" key several times as the computer starts up. Select the "Safe Mode" boot option, log in to your computer and then open the program that you installed.

Step

Press the "Scan" button on the software program to run a system scan for viruses. Once the scan finishes, remove any viruses with the "Remove" button.

Step

Close the software program once the virus infection is cleaned off. Restart your computer and allow it to boot normally.
