Just a little background as to why I like Windows Defender. As a little side job I spend evenings and weekends straightening out computer issues for home users. The majority of my clients use Windows, and most are already up to Win 10.

Over the years I've seen a problem repeat itself. People will buy an AV software and once it expires, they frequently stop paying for it. As we all know, an outdated set of signature files quickly reduces the value of the anti-virus software. And when using free versions of some AV software, they are often running reduced functionality or have frequent nag messages to pay for it. Many users get confused at this point.

With Windows Defender there is no paid version, no nag messages, and no cessation of updates due to lapsed subscription. For me and my clients, this is a huge plus.

Finally, over the years since the days of MSSE and the original "Defender" program I have found Microsoft's security software to be on par with the best free and paid anti-virus software. Now the latest version Windows Defender seems to have upped their game to an even higher level.

Bottom line. Using Windows Defender is IMHO a better alternative than many free AVs and frankly even the paid AVs. It's my default choice for my clients, unless they insist on something else.

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.

Computer security depends more on the user's browsing habits than on the brand of the Antivirus, Microsoft Defender works well and is sufficient on W10, now, it's better to learn also good security practices that an Antivirus doesn't replace.
