   I've used Malwarebytes for years, and never had a problem. Today, it blocked literally every website I had open, and then closed them all when I removed the extension. I usually keep a lot of tabs open for research, and now I'm going to have to look up hundreds of items from scratch.

   I’m sorry you lost hundreds of tabs. That is so frustrating. Unfortunately, Browser Guard incorrectly blocked some legitimate sites because we had a database update that caused a false positive. An automatic fix was deployed shortly after the false positive was flagged. We've also put in additional guardrails to prevent false positives like this from occuring again in the future. This was actually fixed over 10 days ago, so it's a bit odd that you saw it 2 days ago. If possible can you reach out to Support via our chatbot (it will direct to a live person) -- help.malwarebytes.com?

   Depuis la dernière version 3.3.6 "Réputation des résultats de recherche" bug ( sa reste active, mais les recherches reste noir) même chez Edge, au moins avant, sa buggais mais sa marchais, quand on activais sur Firefox. Maintenant c'est pire. c'est pas sérieux. Vous testez avant de le sortir?!! ou y' a plus humain chez vous...

   Good call out! This is unfortunately due to a new feature by Google where the full URL is hidden from us. The black icon indicates it is un-scannable by us. We have identified a way around this and this will be fixed in a future version update.

   Nice intention but too many websites just don't work properly when activated. Especially the Ad/Tracker Blocker practically disables browsing.
   Developer reply · 2 Oct 2026

   Ads/Tracker blocking in general can interfere with sites that are aggressively trying to show ads. That said, it would be interesting to know which sites are giving extra issues, in case there's a bug on our side. If possible can you reach out via the chatbot on help.malwarebytes.com to share more details, please?

   Mate, no other add-on stuffs up as much as this one. Today 50 of me tabs got blocked; I could only remember about ten off the top of me head – the rest are gone for good. That’s why I’m chuckin’ it today; the risk’s way too high. A couple of times a year somethin’ goes pear-shaped, so I gotta switch the add-on off. I’ve had a bloody gutful now!

   I’m sorry you lost your 50 of your tabs, truly frustrating. Totally understand chucking it. The fix for this is already live. We’re also putting in additional guardrails to prevent false positives like this in the future. Hopefully we can gain back your trust at a future time.

   yep nice .. every single website was blocked on my tab. I googled to look how to unblock everything with one click and did everything, even checked for database updates and nothing worked ... everything is still blocked .. had to manually unblock everything .. thank you very much for this work. Something that blocks everything out of the blue is the last thing someone wants.

   Thank you for taking the time to comment. Unfortunately, Browser Guard incorrectly blocked some legitimate sites because we had a database update that caused a false positive. I’m sorry we caused you to have to manually refectify it. An automatic fix was deployed shortly after the false positive was flagged. Don’t hesitate to reach out to our support team if you have any other issues. https://help.malwarebytes.com

   Was great until it decided to block every single one of my tabs. What's wrong with reddit and google searches? And it didn't just block them, 80% of them couldn't be rewound so I lost most of my groups. Seriously, quality check your updates for crying out loud.

   The latest version of 3.3.6 is a mess. It blocked every single tab I had, even the pinned ones. The version was last updated Sept 30, 2026 (today is Oct 1st). It was working all day and then out of the blue it blocked every single tab. What a mess.

   Hi Jayling – This is frustrating, and we feel your pain. Unfortunately, Browser Guard incorrectly blocked some legitimate sites today because we had a database update that caused a false positive. To note, v3.3.6 is totally fine, it was a database update that has since been reverted.

   The latest update blocks the Malwarebytes website itself as unsafe. When someone shows you who they are, believe them.

   Roll back the update. I don't know what idiot authorized this latest update but it's completely broken web browsing. Github wont load the landing page properly and it's just a bunch of text on the left side of the screen and several websites I frequent are being blocked now as "scam" sites, when they arent. In fact I can't get "scammed" anyways because I have an ad-blocker. Roll it back, undo this disaster. Edit: Disabling the plugin until this is fixed.

    Literally blocked my connection to Youtube, Twitch and other obvious not-malware websites just because.
    Developer reply · 2 Oct 2026

    We’re sorry. Browser Guard incorrectly blocked some legitimate sites today because we had a database update that caused a false positive. An automatic fix is already underway via a database update. If you’d like to fix this manually, click the Browser Guard extension → Support → Check for DB Updates to make sure you have the latest database.
