If your computer is slow, getting pop-ups, or freezing, you likely have malware. Windows Defender is great at prevention, but sometimes you need a specialized tool for removal.

Step 1: Emergency Scanners

We recommend these free "on-demand" scanners. They don't replace your antivirus, but they are aggressive cleaners.

  • 1
    Malwarebytes Free The legendary malware hunter. Run a "Custom Scan" and enable "Scan for Rootkits".
  • 2
    HitmanPro A cloud-based "second opinion" scanner that often finds what others miss.
  • 3
    AdwCleaner Owned by Malwarebytes, this tool specifically targets toolbars and crapware.

Step 2: The Cleanup Process

1. Disconnect Internet

Pull the plug (literally) or turn off Wi-Fi. This stops malware from "phoning home" to the hacker.

2. Boot into Safe Mode

Hold Shift while clicking Restart in Windows. Go to Troubleshoot > Advanced Options > Startup Settings > Restart > Press 4.

3. Run the Scanners

Install and run Malwarebytes. Delete anything it finds. Then run AdwCleaner to remove browser hijackers.

How to Stay Safe

The "Golden Rule" of Security

Active Protection > Removal. Cleaning malware is messy and sometimes impossible (like ransomware). Using a top-tier antivirus prevents the infection in the first place.
