I saw one of my tabs got redirected to "blocked by Browser Guard" page and i have realized since then that browser guard scanned all of my open tabs..
I had a lot of tabs open but as i said i only visited Google and Youtube after installing it, unaware that it scanned my already existing tabs so i was clueless as to what was the culprit. I'm also unknowledgeable about what this extension does, from what i've gathered, it protects you from entering malicious sites and it also blocks trackers, ads etc as well on websites but it doesn't scan chrome itself for malware, that's what regular Malwarebytes program is for, correct?
