Halil Halilov (ID: 0000002a40d19c1d) Voted 1 ★ - Updated 08/18/2024 It was good...After the last update something happened ....it brakes web pages it doesn't block properly ads..It block sponsored listing on Amazon and eBay (they are not advertisement) Start changed by 5 to 1...I tried to contact them to report that...it is impossible if you not subscribed to their service...so 1 star and removing it from the browser.

Noël Jörg (ID: 000000fdec583c54) Voted 5 ★ - Updated 06/19/2024 Super Antiviren Programmersatz! Klar ist es nicht so gut wie das Programm selbst, es ist aber immerhin Gratis.

Dr.Ne0Gen3tic (Forensic Buro of Quantum) (ID: 000000804fbaeac1) Voted 5 ★ - Updated 05/02/2024 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.

Marcelo Gabriel Schuster (ID: 000000750fb39040) Voted 5 ★ - Updated 04/07/2024 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

Filip Galetic (ID: 00000030a5f623bc) Voted 1 ★ - Updated 11/17/2023 As of October 2023, no longer blocks ads on YouTube, in fact, having it makes the skippable ads non skippable!
