How to Remove Malware From a PC
Contain first, not cleanup logos: SecurityChecklist treats a suspect Windows PC as contaminated before any product shopping. Stop banking on it, rotate critical passwords from a clean device, then scan with Microsoft Defender (including offline scan options when your Windows build offers them). If free steps leave a residual scare, Malwarebytes is the pack cleanup option (Windows Individual Standard from $59.99/yr on 2026-08-09; Free on-demand cleanup exists per vendor FAQ). Bitdefender is the suite alternative when multi-device always-on coverage is also the leftover job (Antivirus Plus from $24.99/yr first-year). Overall scores stay unpublished (N/Pub). We invent no removal success percentages. Prefer one real-time product. Who should not buy: anyone who skipped the free steps, anyone stacking multiple always-on engines, or anyone who needs verified lab scores before deciding.

How it works
- 1Free
Contain the suspect PC before scanners
Stop entering passwords on a suspect PC when possible. Unplug drives you do not need, note suspicious behavior, and rotate email or banking credentials from a known-clean device.
- Unplug other drives you do not need
- Use a clean device to change email and banking passwords
- Note what suspicious behavior you saw
- Turn on MFA on email after you regain control
- 2Free
Scan with Microsoft Defender
Update security intelligence first, run a full scan, quarantine detections, then reboot and re-check. Use offline scan options in Windows Security when the PC is unstable or real-time protection looks broken.
- Update security intelligence first
- Quarantine detections and reboot
- Consider Defender offline scan if available on your build
- Confirm real-time protection is enabled afterward
- 3Optional paid
Optional cleanup shortlist tool
Malwarebytes is the pack cleanup-focused option after Defender. Prefer official Free on-demand cleanup first when that matches the job; Premium Standard showed from $59.99/yr on 2026-08-09 if you want ongoing prevention. Avoid stacking multiple real-time AVs.
- Download only from the official vendor site
- Run an on-demand scan first
- Reassess whether Premium is necessary after cleanup
- Do not install a second always-on suite beside Premium without a clear reason
- 4Free
Rebuild when trust is gone
If the PC still misbehaves after updates, Defender, and a reputable cleaner, restore from a known-good backup or clean-install Windows. Extra subscriptions cannot honestly guarantee every advanced infection is gone.
- Confirm a backup exists before wiping
- Reinstall only from trusted media
- Rotate passwords again after the rebuild
- 5Optional paid
Product analysis: Malwarebytes cleanup vs Bitdefender suite
Malwarebytes is the incident cleanup lane after Defender (Free on-demand confirm-live; Windows Individual Standard from $59.99/yr on 2026-08-09; 60-day money-back advertised). Bitdefender Antivirus Plus from $24.99/yr first-year fits when the leftover job after the scare is multi-device always-on seats, not another on-demand scan. Scores stay N/Pub. Do not invent removal percentages.
- Finish containment and Defender scans first
- Prefer official Free cleanup before Premium
- Switch to suite seats only when the leftover job is annual coverage
- 6Free
Scenario: redirects after a shady installer, Defender still on
Keep Defender real-time enabled. Run a full or offline scan, then Malwarebytes Free cleanup from the official site if leftovers remain. Do not disable Defender to install a panic suite from an ad.
- Defender real-time stays on
- Official cleaner download only
- Skip dual always-on engines
- 7Free
Scenario forks that change the answer
Banking still happening on the suspect PC: stop; rotate passwords from a clean device before any cleaner logo. Defender full or offline scan already cleared symptoms and habits are healthy: skip paid cleanup this week. Residual scare after free OS hygiene: Malwarebytes Free on-demand cleanup from the official download, keep Defender on. Household also needs annual multi-device seats after the scare: finish containment, then shortlist Bitdefender suite packaging instead of dual always-on engines. System still untrustworthy after updates, Defender, and a reputable cleaner: restore from known-good backup or clean-install Windows.
- Match response to contamination state, not ads
- Refuse dual always-on engines
- Prefer reinstall over endless scanner stacking
