  • (2024-05-19) Halil Halilov: Very good... One of the best...even i can say the only one that works 99.99% of the cases I have regular pages that I visit and they try to flood me with adds (half of the page is ads)...yesterday they try to jump over the Malwarebytes guard...but update came next day...I hade to re-install it to start work...but now everything is blocked again :-))))..
  • (2024-05-02) Dr.Ne0Gen3tic (Forensic Buro of Quantum): Hier steckt wirklich "Technik" und Algorithmen dahinter, denn es ist eine riesige Erweiterung. Die Schutzwirkung ist erstklassig, das einzige was man hier sagen muss ist, dass euer Surfverhalten stark getrackt wird, denn jede Webseite wird an die Server von Malwarebytes übertragen, um sie mit einer Malwaredatenbank abzugleichen. Was dann, serverseitig damit passiert ist unklar und nicht ersichtlich, außerdem werden "Timestamps" [Full] und "Session IDs" übertragen, was "Anonym" sein soll, doch die Vergangenheit hat gezeigt, das allein durch diese Kombination, eine "Deanonymisierung" möglich sein könnte. Die Schutzwirkung ist aber ok, ein weiteres Plus ist ein "Heuristischer Adblocker", der anhand des Verhaltens der "Tracker" erkennt, ob es sich um Tracking oder Werbung oder ähnliches handelt. Auch die Schutzwirkung ist ok, es werden einige Datenbanken heruntergeladen und auch online abgeglichen und somit schädliche Webseiten blockiert. Was diese App nicht kann und auch nicht ist, ist ein Malwarescanner im eigentlichen Sinne, Downloads werden blockiert wenn sie schädlich sind, aber der Virenscan ist hier nur ein rudimentärer, einfacher Ansatz eventuell mit Hash Gegencheck wie es der Chromebrowser auch macht, aber einen richtigen Tiefenscan von heruntergeladenen Dateien mittels Carvingtechniken oder ein Entpacken von gepackten Dateien die heruntergeladen werden und ein Gegencheck aller im Archiv befindlichen Dateien sucht man hier vergeblich. Bei den Downloads werden hier nur einfache Ansätze zur Erkennung verfolgt, auch der Malwareschutz basiert eher auf präventiven als auf proaktiven Maßnahmen, d.h. es soll eher von vornherein sichergestellt werden, dass schädliche Webseiten besucht werden.
  • (2024-04-07) Marcelo Gabriel Schuster: amei de+ esta extensao ela detecta qualquer tipo de malware nao deixa passar nenhum e bloqueia rapidamente sites maliciosos antes que eles carreguem isso e bom pra gente como adulto mas otimo para crianças que so querem saber de entrar no friv ou poki pra jogar enfim otima extensao recomendo muito detecta ate malware em dowloads
  • (2024-01-25) Z-0N: Hey Malwarebytes! Please fix the browser guard extension! It stops working upon closing down chrome, the only fix for this it seems is removing the extension from chrome entirely, then readding it back to chrome. upon closing chrome it deactivates and says that it requires you to subscribe to premium. Very strange! it stopped blocking cookies and ad/ trackers too! i had to manually block them on chrome.
  • (2023-11-17) Filip Galetic: As of October 2023, no longer blocks ads on YouTube, in fact, having it makes the skippable ads non skippable!
  • (2023-11-14) William Feely: Malwarebytes client doesn't recognize installation of the add-on, both on version 4 and on 5 Beta.
  • (2023-11-07) Muhammad Rifal Hafizd: youtube detects this as an adblocker
  • (2023-11-07) Skeptik: I'm getting blocks from this app on websites I know for a fact don't have any harm to them. This is giving too many false positives.
  • (2023-11-04) Roblox Secure: I don't know whats with the bad reviews. It blocks almost all harmful sites and the detection ratio is amazing! The ad blocking is perfect!
  • (2023-11-01) Kärlîtä Rödrîgúëz: En lo personal a mi siempre me a gustado esta extensión para navegar tranquilamente por internet sin tener problemas con las amenazas de virus y poder disfrutar de la reproducción de videos sin anuncios, pero ahora ya a comenzado a fallar en el aspecto de que no bloquea los anuncios de YouTube, me gustaría que solucionasen, extraño no tener que esperar largos minutos de anuncios..:¨) 💔
  • (2023-10-28) Jupiter 0000: Sprawdziła sie, polecam
  • (2023-10-27) Ванёк: Агонь!
  • (2023-10-25) Geesy Swan: installed malwarebytes once, now every website thinks i have adblocker, even after i uninstalled malwarebytes and everything. avoid if you want to use websites with adblocker prevention
  • (2023-10-21) Luk Caluwaerts: AD-Block Plus + Privacy Batcher + Ublock Origin + GDATA + FREE AVAST + Malwarebytes + Superantispyware = 8 Layers of protection + PROTON VPN FREE. No more malware, viruses, ransomware
  • (2023-10-19) Brett: The review down below that claims this extension installs viruses is utterly nonsensical. It doesn't. That's not to say, however, that it's good. It isn't. It's not so much a case of it being bad, but rather of other extensions doing everything better. Want to block ads and trackers? uBlock Origin is the gold standard. Want protection from phishing and other malicious websites that doesn't compromise your privacy? Get Emsisoft.
  • (2023-10-18) Sanaralerx: YouTube seems to detect it as an Adblocker and will disable access to videos. Disable the adblocker and install a better adblocker (uBlock Origin)
  • (2023-10-18) farrier noire: DO NOT INSTALL! Malwarebytes Chrome Extension installed 2 malware viruses; Presenoker and HotCleaner. Both viruses disguised themselves as "Appnhost", on separate occasions, which looks and seems like a regular Windows program (because it is, but the viruses take over the name and app itself. This malware will NOT let you delete the Malwarebytes root folder or any other folder that requires Administrator privilege's. It denies you from changing security changes, like accessing a folder as an Administrator or not, changing principles, inheritance, etc.. If that wasn't enough, HotCleaner hijacks your browser, rerouting whatever you do through Microsoft Bing, all in the while of stealing your information behind the scenes, thus showing a ton of pop-ups, all of which are malicious because it's derived from HotCleaner, not whatever actual advertisement company that's shown on the ad. Do not install unless you want to reset your computer, reinstall Windows on your PC, use System Restore to an earlier point in time (although many people say this doesn't get rid of the malware, so it's best to do a complete reset of the PC). Malwarebytes does have a support/troubleshoot tool that has worked for many other people that have experienced this problem. I forgot to mention that Malwarebytes is BLOATWARE to the extreme. Almost as bad as GeForce Experience/NVIDIA. It'll have. I just installed it and within seconds of the installation, there are 5.. FIVE background processes that are taking up roughly 20% of memory. The extension reloads itself every so often, inflating your CPU and memory percentages, slowing down your PC. TL;DR - Don't install Malwarebytes. I've had it on numerous occasions where it has worked "fine", but it only takes once for it to inject malware into your PC, and it gives not one but TWO malware/viruses/trojan's.
  • (2023-10-17) Cody Claxton: Malwarebytes claims they don't support web browser malware defense. There is clearly a extension but they just avoided my issue entirely. I have a malware infection causing a constant popup window with ads. Malwarebytes did not detect it, and when I asked them to help they just repeated to me what information we can all find on a google search. I demanded a refund, which they granted. But I would not trust their malware software.
  • (2023-10-16) Dimitar Qvorov: The best and most solid Chrome protection against malicious websites. Top tier
  • (2023-10-15) JinOldGamer: Simple et très efficace, certainement l'une des meilleures si ce n'est la meilleure dans sa catégorie.
  • (2023-10-14) SR world: Nice extension, Although i have ublock adblocker, I needed some protection too!
  • (2023-10-13) Абоба: Имба
  • (2023-10-11) Johny Marochnic: great extension that I've been using since it came out, but when I want to watch YouTube videos I have to delete it I hope you fix it, I don't want to delete the MB. Blocking videos is a violation of YouTube's terms of service It looks like you may be using an ad blocker. Unless YouTube is whitelisted or ad blocking is turned off, videos are blocked from playing. Thanks to ads, YouTube can be used by billions of people around the world. To watch ad-free content, subscribe to YouTube Premium. Authors can continue to get paid from your subscription
  • (2023-10-10) droptozro: Been great since I started using it a few months ago. But the Youtube ad-skip/block is no longer working. Please fix that. It's the primary reason I'm a subscriber and user of MalwareBytes.
  • (2023-10-10) Сергей Артамонов: прога нашла 4 вируса ,который не видел касперский ,удалил ,теперь думаю переийти с касперского на малвери
  • (2023-10-10) Ernst Sigl: Its the best filter of baddies I have seen. It is fast and from my many years of experience, no other Browser Guard comes close to Malwarebytes efficiency. If a website I know is clean but complains that i must show the ads, I just turn it off for that site. It remembers it and I have no more pop-ups complaining.
  • (2023-10-10) Ciyei: Muy buena aplicación para la seguridad ♥
  • (2023-10-08) Abdul Baqi: youtube videos not working if ad blocking is ON
  • (2023-10-06) - N: 有用
  • (2023-10-05) Stefano Salezzari: io sono uno smanettatore e guard mi risolve un tot di problemi quindi 5 stars
  • (2023-10-03) AGGRESS1VEX: Хорош!
  • (2023-09-28) David Balascak: It has been causing chrome to freeze up. there needs to be an update for this lockup problem
  • (2023-09-21) Fernando Taddeo: Best antivirus
  • (2023-09-21) uglyzodiac (Rue): Me gusta bastante, pero tiende a crashearse de forma continúa. Espero puedan resolver eso, de lo demás es muy buena aplicación.
  • (2023-09-21) Andrei-Cosmin: One of the best extensions for safe browsing and enhanced security. This extension enabled with enhanced browser setting from google chrome is the best way to protect from malware and other tracking adds and scams websites. Malwarebites browser guard is the best! Keep up the good work and thanks for all security protection!
  • (2023-09-20) Turgut Yüce: Mükemmel
  • (2023-09-17) Vince AKA Wolfe Pignotti: No one has managed to refine and make a better Browser guard In my opinion this browser guard has never let me down even on u tube..... VR Wolfe
  • (2023-09-16) J J: It's a useless extension by a good brand. I use Ublock Origin, it's 100x better and 100x more effective. Don't waste your time with it. They get your browser info and offer nothing in return
  • (2023-09-15) Keith Williams: Brilliant app, been using for years, mostly to block youtube ads. From today though that functionality no longer works - I'd forgotten how tedious unskippable youtube ads are :-(
  • (2023-09-12) Андрей Гуртовой: Не нравится Хакерам вот и критикуют, да определяет, да блокирует. Удобные расширенные настройки, белый черный список. С другими расширениями не конфликтует еще и бесплатный. В рот компот тому кто ,,Даренному коню в зубы смотрит.,,
  • (2023-09-11) Ritzarnt: Extensão boa detecta malwares e sites maliciosos, a internet hoje está cheia de malwares sempre é bom usar esse tipo de extensão para o navegador ficar seguro. além que há sites com trojans e a gente nem imagina e a extensão detecta. enfim 10/10 recomendo!.
  • (2023-09-04) Sergio: APRESENTANDO CONFLITO COM Componente de Segurança Bradesco. O site do banco carrega normalmente quando remove a extensão...
  • (2023-08-28) Tulio Castillo: Es muy funcional para la detección de páginas de virus.
  • (2023-08-27) Sumudu Ranathunga: Now, for a few years, I've been using the Malwarebytes extension for all my web browsers. It is highly effective for security and it works as an adblocker. There are a lot of rip-off gold-digging apps doing the same thing with the high paywall. But Malwarebytes give everything for free. This is an underrated app. I highly recommend this extension as an extra protection layer for every web browser.
  • (2023-08-27) C O: I have Malwarebytes Pro. I have been using it for many years & I am very happy with it. PLEASE add the Brave browser to the browsers you support. I only use the Brave browser. You currently support Chrome, Firefox & Edge. The Brave Browser has saved me from hours of unwanted ads & popups unlike Chrome & Edge. Thank you in advance.
  • (2023-08-22) Gabriel Morales: Se me elimino sola, sera peligrosa?
  • (2023-08-22) Tongs: Pop up and spam blocker that's about it. Offers minimal protection against malware that does slip through the cracks. Is this extension still updated? it could be better.
  • (2023-08-21) Dave “Balbotoys” Balboni: Funziona, nulla da dire ma nel mo caso specifico troppi falsi positivi. Ingestibile
  • (2023-08-16) Luis López: Le cambiaron a color blanco el ícono de la extensión y se ve muy mal.

  • (2019-05-18, v:1.0.44) Aaron Hodge: Suddenly started blocking Netflix
    I started getting an error message when trying to view Netflix (Netflix Error M7034). I disabled all of my extensions in Chrome and re-enabled them one by one. It came down to the issue being with the Malwarebytes Browser Extension. I tried whitelisting the site and even using the slider to turn off the adware and malware protection. The only way I could get it to work was by disabling the Extension as a whole. I am a Malwarebytes paid subscriber and love the Malwarebytes products, so I would like to see this resolved.

  • (2019-05-10, v:1.0.44) DENNIS PRIMM: TV Guide Webpage Not Loading
    I just installed your browser extension yesterday and it worked PERFECTLY then, but today when I tried to load the TV Guide webpage (https://www.tvguide.com/listings/#favorites) it came up blank for some reason. Yesterday it loaded the fastest it has ever loaded ever!!! I was so happy!!! Please note: I'm using Adblocker Genesis Plus in conjunction with your extension and it didn't cause any problem yesterday. Today I turned the Adblocker Genesis Plus off and kept your extension on and the TV Guide webpage would still not load, but when I turned your extension off the webpage loaded again albeit slowly as it had in the past. Could you please let me know how to get around this? Is there something I could change in the "Settings" to make it work like it did yesterday? I did not touch anything in the Settings yet, but would be more than happy to make changes to get it to work like it did when I first installed it. I really love your products and have Malwarebytes Premium on my computer and my Samsung smartphone too and tell all of my friends to install it on their computers/phones as well. Thank you Malwarebytes for making such great products!!! :-)
