Windows Defender Browser Protection

I'm a fan of Windows Defender. I've written about it several times.

In April 2018 Microsoft introduced Windows Defender Browser Protection for Chrome.

Yeah, you read that right: For Chrome

It's a Chrome extension. In less than a month it had more than 64,000 users and a 4 1/2 star rating in the Chrome store.

Here's (archive.is) Microsoft's product page.

Here's the description from the Chrome store:

The Windows 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, Windows 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, Windows 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.

It doesn't seem to take up much memory.

Why not?

Oh, don't look for their privacy policy. But you're running Windows 10, aren't you?
