I don't mind defender, mostly because I don't want to pay for standalone AV again (mostly because you have to pay a subscription), but at the same time I hate how relatively unconfigurable it is.
What more would you like to configure and why?

In a perfect world there are no viruses and no malware. No one wants to hack into your PC or steal your data.
Until we achieve that - putting aside the issue of it being realistic - a fairly robust, rigid, universal and widely-available security suite is really the second best option.

Windows defender won't stop viruses. Better to delete it and install malwarebytes for example

Actually it will - and isn't half bad at it.
Malwarebytes may be better at malware, but is a lot more focused. It's a good addition to Defender, but surely not a replacement.

Why though? You can run them together. How bad is the performance hit on a modern machine?

Im just going to interject here Incase this is in fact the question you are asking. I’m on mobile so forgive line breaks.

you should NOT run multiple active AV on a system. And it has nothing to do with today’s PCs.

that’s a common misconception I don’t think it was ever about PC performance. Though with an HDD you really notice.

the problem lies in the actual engines and the potential to detect each other. Another huge problem is simultaneous file locks. You really just should not do it.

bit this statement has nothing to do with the OP so apologies

Shows what I know haha.

I get that you generally don't do it, but hasn't mb been the exception for a while? They can be configured to step out of each other's way. I dunno, maybe I've gotten lucky but it's never caused me any of the issues you mentioned.

Like I mentioned active. Do you have the always on malwarebytes or just the scanner? That doesn’t matter. In the case of stepping out of each other’s way, that’s only true for defender and another AV that plays by MS rules of integration.

install norton and MCCaffrey next to each other, vastly different experience.

Mmm... definitely. I am also on my phone and at work so I'm not being very clear.

The standard way to run them together is to let Windows defender hand off the real-time protection to mbam. Wd will still update and run scans.

This can all be done as a part of setting up mbam.

Just seemed like a no brainier to me. What I wasn't getting was going through the trouble to actually gut wd when actually they know how to work together out of the box. All it's doing at that point is updating and scanig when the PC isn't in use. No perf hit outside of mbam, which also isn't bad ime.

Or you could keep wd rt protection and run mbam free for its scans. Which is probably a good, lightweight answer for most people.

Someone at my parent's house did something that allowed malware through. Windows Defender stopped, and quarantined one but didn't detect four more hiding in the ProgramData directory that Emsisoft Emergency Kit found. Mom was complaining about all the web browsers having search changed to Yahoo! when she wanted DuckDuckGo.

Had a similar experience with that one once... good one to have in your toolkit. But I avoid thier suite like the plague. It works okay, but it's bloat city and the interface wasn't great imo.

I just googled "disable windows defender"
If you did the gpedit.msc move go for the regedit move :
  1. Use the Windows key + R keyboard shortcut to open the Run command.
  2. Type regedit, and click OK to open the Registry.
  3. Browse the following path:
    HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender
  4. Right-click on the Windows Defender (folder) key, select New, and click on DWORD (32-bit) Value.
  5. Name the key DisableAntiSpyware and press Enter.
  6. Double-click the newly created key and set the value from 0 to 1.
  7. Click OK.
  8. Right-click on the Windows Defender (folder) key, select New, and click on Key.
  9. Name the key Real-Time Protection and press Enter.
  10. Right-click on the Real-Time Protection (folder) key, select New, and click on DWORD (32-bit) Value.
  11. Name the key DisableBehaviorMonitoring and press Enter.
  12. Double-click the newly created key and set the value from 0 to 1.
  13. Click OK.
  14. Right-click on the Real-Time Protection (folder) key, select New, and click on DWORD (32-bit) Value.
  15. Name the key DisableOnAccessProtection and press Enter.
  16. Double-click the newly created key and set the value from 0 to 1.
  17. Click OK.
  18. Right-click on the Real-Time Protection (folder) key, select New, and click on DWORD (32-bit) Value.
  19. Name the key DisableScanOnRealtimeEnable and press Enter.
  20. Double-click the newly created key and set the value from 0 to 1.
  21. Click OK.
After completing the steps, simply restart your computer to disable the Windows Defender Antivirus permanently.
If you change your mind, you can always revert the changes using the same instructions, but on step No. 3, right-click the DisableAntiSpyware key, and select Delete. Then inside the Windows Defender (folder) key, right-click the Real-Time Protection (folder) key and select Delete to remove key and its content. Finally, restart your device to complete reverting the changes.

You don't need third party programs to do this or else you are just lazy :p
Third party programs tend to let you think they can block telemetry. Ok but they tend to break the store and many things you could find useful by deleting them...
You want a good thing for your paranoia obsessions ? :D Get a firewall (the windows one is just crap) and lose some time asking for ANY connections. It's time consumming the first days but once you got your firewall rules set up without having your system broken you are gold.
Also you don't need to have a 24/7 antivirus if you think you know what you are doing. Once a month download a trial from Kaspersky or Bitdefender (depends if you are more Russia or USA) and scan the whole system to be sure it's fine. A good program I know too is Rogue Killer. Take the free version (no autoupdate, no custom scan) and run it once a month if you feel your computer is in danger :D
Some people want to cut all the microsoft telemetry but take 24/7 antispyware/antivirus which spy them all day long...that's nonsense.
I won't judge if you want to feel safe but the question is, is everything really safe with 24/7 programs scanning all your datas ? I still can't answer this. Up to you.

Edit : about firewalls I use NetLimiter 4 Pro and it's doing the job. Many firewalls can do the job, it's just a bit of work being harassed by connections demands, checking what the services asking for internet are doing and all but it's a good move in my opinion.

This procedure does not work for 1909, to disable Real-Time Protection. Only works for 1903 and earlier .. !!

Yes, the two of them actually complement each other. Malwarebytes has actually worked with MS to make it so, since MBAM is not an antivirus. There are a few more that also are good with it as well.

They’ve also worked with Bitdefender so they play nice together, both resident.

Plus, I note now it is called Microsoft Defender because it is much more than just a malware scanner for Windows, the OS. For example, the built in firewall is part of Microsoft Defender.

AV, Defender, is not just scanner. It is anti-malware engine (service). And don't have integrated firewall. Microsoft just used name Defender for firewall already integrated in OS. They want to show users that in OS is also firewall. Just stupid marketing.

You have no chance to defend yourself on Internet without always running anti-malware engine. Only AV scanner is useless.

Windows Firewall now stup* named Windows Defender Firewall is advanced firewall with all needed features for desktop. In OS with some modifications is since Windows XP SP2. It is NOT part of AV. Easy config from Control Panel. On/Off using "Turning on or off". Basic configuration using "Allow an app or feature through" and advanced configuration using "Advanced settings" or CLI.

People always say this. I must be interneting wrong.

Sounds like you are splitting hairs, honestly. Who cares under what name they bundle it?

Just realized the OPs question was probably answered long ago. Per usual the back and fourths happen with no end in sight.
