Can Doing a Factory Reset Destroy a Virus? (2024)

Running a factory reset on a computer is an effective way to clear out a persistent virus or other malware you can't otherwise remove. Running a factory reset, also referred to as a Windows Reset or reformat and reinstall, will destroy all data stored on the computer's hard drive and all but the most complex viruses with it. Viruses can't damage the computer itself and factory resets clear out where viruses hide.

Running a Factory Reset

  1. Running a factory reset will return the computer to its initial power-on state, as far as the operating system and storage devices are concerned. To run a factory reset, open the Charms bar, select "Settings," tap or click "Update and Recovery," choose "Get started" under the "Remove everything and reinstall Windows" heading and follow the on-screen instructions. Choosing the "Fully clean the drive" option will most likely destroy all viruses.

Viruses That Escape Resets

  1. Factory resets don't remove infected files stored on backups: viruses can return to the computer when you restore your old data. The backup storage device should be fully scanned for virus and malware infections before any data is moved back from the drive to the computer. Some very rare viruses can find ways to evade factory resets: using a boot and nuke program and re-installing Windows from scratch can destroy such viruses.
