Key Takeaways

  • Disconnect: Unplug from the internet immediately to stop the malware from sending data.
  • Safe Mode: Boot into Safe Mode so the virus doesn't load with Windows.
  • Scan: Use Malwarebytes or Windows Defender to hunt it down.
  • Change Passwords: Assume they were stolen. Change them AFTER cleaning the PC.

Signs of infection: Your homepage changed, your fan is running full speed (cryptominer), or files are disappearing.

Step 1: Enter Safe Mode

In Safe Mode, only the essential parts of Windows run. Most malware cannot start in this mode, making it easier to delete.

To enter Safe Mode: Hold Shift while clicking "Restart" in the Start Menu.

Step 2: Run a Scanner

We recommend Malwarebytes (free version is fine for cleaning). Install it, update the database, and run a "Threat Scan". It will catch things traditional antivirus misses.

The "Nuke it" Option

If the virus keeps coming back, the only 100% safe solution is to Reinstall Windows. Backup your photos/docs to a clean USB drive, then wipe the drive and start fresh. It is painful, but it works.

Frequently Asked Questions (FAQ)

Can I trust "PC Cleaner" apps?
No! Most "Speed Up My PC" or "Driver Updater" tools are scams or malware themselves (Potentially Unwanted Programs - PUPs). Stick to reputable names like Bitdefender, Malwarebytes, or Windows Defender.
How did I get infected?
Common vectors: Email attachments (PDF/ZIP), cracked software/games, or fake "Update Flash Player" pop-ups on streaming sites.
