Advice Request Antimalware core service running alongside 3rd party antivirus

[Parkinsond]

In fact, since Microsoft Defender protects so well, is pre-installed, and is lightweight, I no longer find a need to download any 3rd party AV.

I've noticed that Microsoft's pre-installed software are now sufficiently good, which has led me to abandon many of the other software I used to use previously.

MSD indeed is very good; lacks two things, improving web protection (SS is not that good) and redesigning its firewall (when trying to create allow outbound rule for a program using specific ports it fails to connect).

Yes it's already a point where MS Defender is mature enough with good detection rate. When MS started with MS Security Essentials, it's not on the same level with the well known AV in the market.

Those days I was using Norton (my very first AV).

I agree with you on that, but browsers these days block most threats, and by adding an ad blocker you can be more secure.

Speaking about browsers, AVG has just glitched and inserted its own certificate with Reddit.

 

[stonjean633]

Yes, it worked Many thanks

Glad it worked. Sometimes uninstall/reinstall causes unknown problems especially in the antivirus software.

 

[lokamoka820]

I was using K free before AVG free; never had this issue with.

I remember discussing this in the past, you can read in this thread from this post:

Advanced Plus Security Post in thread 'Brambedkar59's Security Config 2026'

What was the problem with AVG Internet Security?

Read post #124 of this thread.

When you use Kaspersky, did you disable Microsoft Defender or just install Kaspersky and let it disable it by itself?

I disable defender because I don't like it running in background. I reenable defender each month so it can update components via Windows Update.

the problem with this approach is that sometimes AV certificate is not up-to-date as browser own certificate.

Fixed by restarting Windows; looks like a glitch after enabling the passive mode and disabling it.
Avast-AVG is the second most glitchy after B.

My problem with Avast/Avg is that they start light, then after a week or two they become heavier.

Same here.

I have the same issue and thought it was just me.

Microsoft Defender is running in passive mode and shows up in task manager.

But periodic scanning is disabled, SAC is disabled, and I have another anti-virus registered and running.

I've tried installing other anti-virus software and Microsoft Defender is always running on this Windows 11 computer.
I've tried toggling AVG passive mode and restarting, and it doesn't change anything.
Although, I have another Windows 11 machine, and it doesn't have this problem.

Toggling AVG passive mode fortunately worked for me; if it did not work, I was going to try to reinstall, or at least repair install, of AVG.

Try this sequence.

Turn ON AVG to passive mode then restart

Then turn Off AVG passive mode then restart.
See if that works.

Restarts can sometimes work like magic, for a variety of issues.

Yes it does. One of the basics.

Tried restarting Windows, but did not help; only toggling passive mode of AVG.

 

[darth]

No luck

I tried enabling AVG passive mode, reboot, disable AVG passive mode, and reboot. Defender is still running and in passive mode

I've tried uninstalling AVG and installing Bitdefender Free. Defender still running again in passive mode

I've tried uninstalling all 3rd party antiviruses, and installing SEP. Defender still running in passive mode

It's so annoying, even with Defender in passive mode, it's still receiving definition updates and peaks up to 1 GB of memory usage during updates

Thanks for sharing that. I just bought Avast Premium cheap in an online store ($6 for one device/yr), and decided to turn on everything in App & browser control (except for Smart App Control, which cannot be turned on) and Device Security, and followed your Powershell command, and the entries are marked "False".

I found someone asking about this in one thread in the Avast forum, and he was told that the third party AV usually takes over even though the user tries to activate Windows Security features.

Defender for quite some time has been running in passive mode, as of the last major Windows 11 release. It’s running and it’s installing updates. It also protects the integrity of Microsoft Defender.

Are you all referring to the Defender processes? I recently used Kaspersky Standard on Windows 11 Pro 24H2 (26100.6584 build) and did not see any Defender processes listed in Task Manager.
