Download the Malwarebytes Support Tool from their official website. Run it and select “Advanced” > “Clean” > “Yes.” This tool removes hidden folders, registry entries, and license tokens that a normal uninstall leaves behind.

Go to Windows Settings > Apps > Installed Apps, find Malwarebytes, and uninstall.

Download a new installer from the official Malwarebytes site. Install and run it. If you are lucky (and enough time has passed, usually 30+ days since the last trial), you may see a “Start Free Trial” prompt.

Restart your computer. Skipping this step leaves registry keys intact.

The tool will prompt you to restart.

Open Malwarebytes, go to Settings > Account, and click “Deactivate this license” if you have a paid or expired trial key.

In the digital age, security software is our shield against an ever-growing army of malware, ransomware, and spyware. Malwarebytes has earned a stellar reputation as a powerful second-line defender, often catching what traditional antivirus software misses. For many users, the “Premium” trial—typically 14 days of full, real-time protection—is a taste of ultimate security. But when the trial ends, the clock resets to a limited, manual-scan-only “Free” version. This leads to a common question: How can I reset the Malwarebytes trial to get that premium protection back?
