How to Remove a Virus From Your Computer (Step by Step)

Pop-ups, a sluggish system, a hijacked browser homepage, or programs you never installed are classic signs of malware. Here is how to clean it up safely.

1. Disconnect from the internet

Unplug Ethernet or turn off Wi-Fi to stop the malware from spreading or sending your data out while you work.

2. Boot into Safe Mode

Safe Mode loads only essential drivers, which often prevents the malware from running and makes it easier to remove.

3. Run a reputable malware scan

Use Windows Defender (built in) plus a dedicated on-demand scanner like Malwarebytes. Run a full scan and quarantine or remove everything it flags.

4. Clear browser hijacks

Remove unknown extensions, reset your homepage and search engine, and clear cached data. Browser hijackers frequently survive antivirus scans.

5. Update everything and change passwords

Patch Windows and your browser, then change important passwords from a clean device — malware may have captured them.
