Comments and Reviews

   
Comment summary: Microsoft Defender is praised for being pre-installed, free, and effective for everyday users, offering hassle-free updates and decent protection, especially for those not engaging in risky browsing. Users highlight its improved security and low intrusiveness in recent years. However, some report issues with false positives, frequent update-related annoyances, and limited cross-platform support. Rarely, criticism targets system resource usage and questionable background processes.

Spyware GARBAGE from MicroSoft, overloads the CPU, does NOT protect against spyware, runs questionable processes on your PC, discriminates users - some obsessive processes CANNOT be disabled in the program settings or through the Task Manager of Windows, only by blocking through Process Lasso or through the Command Line.

Microsoft Defender runs on Windows –– but not macOS. What alternative do you recommend for macOS?

Excellent cause it is free and works, but capriciously detects viruses & spyware in clean and harmless software. If you tell Defender to ignore a given detection, then in the next update deletes the "offender" again. Annoyingly those updates are very frequent.

I've been using it since the Fall Creators Update and it's awesome. Non-intrusive. Haven't had a virus in over 2yrs with the help of Microsoft Defender.

Has improved their security over the last years. It is not ***t as it used to be.

This has become very decent antivirus product, I can now feel a sense of security of using it. Of course Microsoft has still a lot way to go until it can compet with big AV companies.

I recommend this to people who are just casually browsing the web with an adblock on and without visiting any shady websites and you're good to go but not recommended if you are going to visit the absolute shadiest of all websites.

Windows Defender is also good if you combine it with Malwarebytes (On demand scanning only), it will finish off almost everything Defender wasn't able to clean.
