    Is Windows Defender an AV program, and is it enough?


    When I google what Windows Defender is, it's sometimes referred to as an anti-spyware program, and other times it's called an anti-virus program. Is it both? And is it good enough to use it instead of also getting something like Avast as an anti-virus?
    I would hope that Defender would be best since it is made by Microsoft, which also makes Windows. They would be most likely to know their system the best and how to protect it, right?

    Thank you! From what I've been reading now, it seems to be sufficient. I'm glad that's the case. It saves processing power and don't have to have a large AV app going when it isn't necessary, updating itself, telling me it's out of date, showing me ads, etc.

    The confusion is due to the fact that in Windows 7 Defender was a rather limited anti-spyware program. You needed a proper AV as well and the Microsoft one was called Microsoft Security Essentials (MSE). From Windows 8 onwards Defender became a full blown AV and included all the functions of MSE.

    Yes, it is as good as any of the other top names. In the most recent independent tests it actually scored slightly ahead of Avast.

    Wow! I never would have guessed that to be the case. It used to be that Microsoft and Windows were always lacking things that third party developers would step in to fix. But for MS to actually have the best one is really a big surprise.
    Another surprise in that chart in your link was that Malwarebytes scored at lowest in terms of protection. They are always so highly spoken of.

    Yes, MS used to deserve a poor reputation. With W10 that have worked hard to make sure that is no longer the case. Defender is all I ever use in W10.

    I hadn't spotted that, surprised me too. Looking at the details of the test, seems the were let down by scoring less than 90% on 'Protection against 0-day malware attacks..'.

    Do the 2 programs work together, or does only one work at a time? When I used Avast, it was as if Defender wasn't even there. No notifications from Defender at all. Now that I have nothing but Defender, I see it's notifications. Does that mean when I had Avast or Malwarebytes, Defender was turned off? I'm hoping that maybe if I had another AV app, such as Malwarebytes, then Malwarebytes could do what it can, and then Defender could catch what Malwarebytes may have missed. At the same time, Malwarebytes might even do things Defender doesn't do. The 2 programs could complement each other. Does it work that way?

    Hi there
    latest releases of Windows 10 together with the soon to be renamed WD to "Microsoft Defender" is absolutely all you need plus "Brain" to detect scams / identity fraud etc which AV software isn't equipped to deal with.

    Ms makes most of its money these days on its Cloud AZURE services, A.I and consultancy so it wants to ensure that the security systems it has in place is as rigid as it can be.

    In any case since WD is often updated as much as 3 times a week as well as Windows itself I can't really see how any 3rd party AV suite could possibly keep up with the Ms updates so my view here is that you are only "buying needless trouble" by adding 3rd party stuff to a perfectly robust and functioning product.

    I wonder how many people out there using Windows 10 at build 1903 (not the earlier builds) with WD and malwarebytes -- has Malwarebytes ever found anything that WD has missed -- I suspect probably not --note I'm only proposing this for Builds of W10 at level 1903 -- earlier builds - who knows.

    Cheers
    jimbo
