Bob,
Exception is that Defender does NOT disable itself when another AV is installed on Windows Server platforms. When Avast or other AV is there it still runs and you have to take steps to remove it from the windows features settings.
Cheers,

Thanks for the information.
Windows Defender haven’t Behaivoral detection
Avast = 9 (settings bad for 1 point down(i sended too many feedbacks to avast already i think they are working on it).)
Defender = 1 (only a antivirus 
)

=======================================================
Windows Defender AV initially flagged the attack’s unusual persistence mechanism through behavior monitoring, which immediately sent this behavior-based signal to our cloud protection service.
Your knowledge of Defender is certainly lacking for a proclaimed security expert :
There is a difference between calling yourself an expert and
actually being an expert.
There are also some choice words reserved for self praise.
So is Defender safe to use for protection in folks eyes, or is it not safe to use in terms of normal every day protection for Windows 10 Based Machines, Seen a lot of info lately that all folks need is Defender and Malwarebytes to have good protection, unless i’m wrong in that thinking or believe other so called security experts more than I should
It’s your computer. My systems continue to be protected by Avast as they have been since 2003.
Well This morning went to Switch back to Avast from Defender on my Windows 10 Pro Desktop, went to remove the exclusions from Defender, and turn off some other settings with 3rd party app–Configuredefenderx64, then bsod occurred–Process Locked something it said, then it restarted, then I looked up what to check, ran sfc /scannow, ran dism online /cleanup image next, Heres where it gets interesting—ran chkdsk /r D:, let it run, did not touch the PC period while it was going for those 2 hours
When it finished I discovered all the files was missing–like totally
931gb free it said of 931gb
then ran Western Digitals Lifeguard software, ran smart quick and extended–all passed
then did a complete clean install, got all the drivers in, then did system image after that
Seems to be running perfectly fine now
(and yes Avast is reinstalled)
Now if I ignore those other forums, i’ll be able to feel good on leaving it in again
Of course it is, Defender in Windows 10 provides excellent protection and it’s not necessary to have Malwarebytes running in real time, heck! I don’t think I’ve used my Malwarebytes Pro once in the last year or more
Using the built in Edge Browser also adds some extra security via Windows SmartScreen plus it includes “InPrivate” for banking and such where you don’t want your details tracked.
what happening i only said basic things
now you wanted

Using an old link that doesn’t work isn’t very persuasive.
Its not old, from August 6, 2019. I screwed up I guess posting the link, just copy and paste it in your browse to view.
Somehow or other the URL you posted had FTP (not HTTPS) at the start of the underlying URL and not what was shown on the screen.

This one works.
One good report also doesn’t make it the top of the class.
Those test scores vary from month to month.
Windows Defender lower than avast
it is guarenteed from me.
i will do a test and share it here with screenshots we can look windows defender vs avast
Results from legitimate and professional testing companies are quite welcome, If your personal tests are like your personal opinions below then they’re not even believable and are completely amateur without facts and figures
avast better.
