What our analysis found

Malwarebytes Browser Guard, used by 11,000,000 people, showed no malicious code in Extension Auditor's review. Its permissions mean it can read and change data on all websites, can inject scripts into pages and can observe network requests. It comes from a trusted publisher and was last updated in September 2026.

The extension is a well-known security product from Malwarebytes, a reputable publisher with a Google trusted badge. All permissions are required for its ad/ tracker/ malware/ phishing blocking functionality. Source code analysis shows no unauthorized data exfiltration or suspicious behavior; network communication is limited to the publisher’s own domain () and Sentry for crash reporting (). The ML model likely overfit on permission breadth, regex pattern counts, and file counts that are typical for a large, complex ad‑blocking and security extension.

THE BEST TYSM !

Bella Rana (Muffin)·5 Oct 2026

I've been using this extension for 2 years and it's never given me any trouble, but lately with the stupid way they're using their damn AI it's flagging all my tabs as “Dangerous Sites” even though the ones I have open are Pinterest, WhatsApp, or even YouTube. Fix your damn extension, it used to work fine.

Naru·3 Oct 2026

Colossally bad software. Abruptly blocked virtually every tab on my Chrome browser, even ones I had not opened. Previous bad experience with the function that inspects the clipboard, such that I had to turn off that permission. This company is incapable of producing a reliable, dependable product, and obviously engages in no meaningful testing before making updates live. Overall, the hassle makes this product more trouble than it's worth. And the company is offering no recompense for all the injury it caused to (undoubtedly) tens of thousands of users. I have turned off this extension. At some point I will uninstall it. Malwarebytes has forfeited my trust.
