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.

Chrome系の各ブラウザのセキュリティ強化にうってつけと思われます！ 設定もシンプルで、扱いやすい！！
実際は4.5。 日本語対応すれば星5
cũng ok
круто конечно,но блокирует на рандом. Лучше скачать malwarebytes browserguard. а так норм
works very efficiently and i am free from pop up adds from unwanted sites. I am giving this star and I want it to be improved.!!!!!!!!!!!!!!!!!!!!!!!!!
トロイの木馬など分かりやすいウイルスは事前にブロックしてくれます。 危ないサイトの場合警告が出るので、クリックしてしまっても入る前に戻れます。 pc内臓のWindowsディフェンダーと合わせて使うといい感じだと思います。 ただ、有料ウイルス対策ソフトのように「事前ブロックをしました」と通知が出ない点が不満。
これを有効にすると、 価格コムとか攻略サイト、エロサイト 見てると画面が点滅（一瞬だけブラックアウト）する。 これが警告なのか？
I guess it worked fine, until it didn't. Now it's flagging my AOL inbox repeatedly, closing the site and presenting a great big red warning. I have to keep going down to the bottom of the alert and select "Continue Anyway (not recommended)" Problem is, it's loaded by policy onto a work laptop and I can't switch it off or disable it. Big PITA right now.
