Is your browser plagued by constant pop-ups, unwanted toolbars, or has your homepage been hijacked without your consent? These are classic signs of adware or Potentially Unwanted Programs (PUPs) infiltrating your system. While traditional antivirus software is essential, it often misses these pesky and intrusive threats. This is where Malwarebytes AdwCleaner excels. This detailed guide will walk you through how to use this powerful, free, and targeted tool to clean your computer, restore performance, and reclaim your browsing experience.
What is Malwarebytes AdwCleaner?
Malwarebytes AdwCleaner is a specialized, free utility designed to hunt for and remove advertising-supported software (adware), browser hijackers, toolbars, and PUPs that often slip past conventional security software. It’s renowned for being lightweight (under 10MB), fast, and requiring no installation—you can run it directly from a USB drive if needed. Developed by the cybersecurity experts at Malwarebytes, it uses a focused database to target only unwanted software, making it a safe and efficient supplement to your primary antivirus.

1. Analyze Results: Once the scan finishes, AdwCleaner presents a categorized list of all detected items (adware, PUPs, browser policies, etc.). You can expand each category to see details.
2. Choose Items to Remove: Review the list carefully. The tool allows you to deselect any item you believe is a false positive. For most users, it is safe to proceed with all items selected.
3. Execute Cleanup: Click the "Clean & Repair" or "Quarantine" button. A warning will appear, stating that all open programs will be closed to complete the removal. Save any ongoing work and click "Continue".
