The Microsoft Defender Browser Protection extension helps protect you against online threats, such as links in phishing emails and websites designed to trick you into downloading and installing malicious software that can harm your computer.

If you click a malicious link in an email or navigate to a site designed to trick you into disclosing financial, personal or other sensitive information, or a website that hosts malware, Microsoft Defender Browser Protection will check it against a constantly updated list of malicious URLs known to Microsoft.

If the malicious link matches one on the list, Microsoft Defender Browser Protection will show a red warning screen letting you know that the web page you are about to visit is known to be harmful, giving you a clear path back to safety with one click.

Având în vedere că nu prea suport să-mi mănânce resurse un antivirus și am dezactivat chiar și windows defender din pc, un mic plus de securitate e bine venit! :)

I'm only rating it 1 star so Support notices the issue. The extension does not work in the latest Brave, v0.55.22 Chromium: 70.0.3538.77 Stable, x64 version. Nothing gets intercepted or blocked, meanwhile the same URL does in any other Chromium based browser.

Hello, I would like to see this extension improve to become equal to or surpass the protection available in Microsoft Edge and some other products that outperform even Microsoft Edge. There is a thread at the MalwareTips Forums called, [Updated 25/7/2018] Browser extension comparison: Malwares and Phishings, where some issues with this extension have been noticed like: This extension requires a recovery time between detecting links if you try to throw more than one link at it, its detection is always worse than Microsoft Edge's by a somewhat large amount and there are several other products that usually perform better, in incognito mode the block page does not seem to work, there is possibly not a section in the privacy policy about this extension, there is not much documentation for this extension, this extension lacks a section in the forums or a support section here and emails to the support email address are possibly not replied to, on one of Microsoft's test pages this extension fails to block some of the test links / files, and so it would be nice for the developers to follow that MalwareTips thread and address these issues. I would like to also suggest adding the ability to report websites and other issues through the extension itself, maybe add ratings for search results (web, image, video, et cetera), maybe consider adding an adblocking option (like maybe forking uBlock Origin into this extension or just add some adblocking list options), add the option for automatic submission of suspicious and unknown websites et cetera, and improve malware / grayware / et cetera detection to match or surpass some of the products tested in that MalwareTips thread. This extension has potential so I hope to see it improve, thank you, and keep up the good work. -John Jr
