MRT RAM consumption issue - Catalina

[singyuk]

It sounds like MRT is reacting to something in your system. Google Chrome is known for getting everywhere.

As @pastrychef says, try removing these apps until MRT settles down. Then you'll know if it is something else.

Ok, I will try.

Check to see what you have in:

/System/Library/LaunchAgents/
/System/Library/LaunchDaemons/
/Library/LaunchAgents/
/Library/LaunchDaemons/
~/Library/LaunchAgents/

If you have malware, these are the most common places they will reside.

With Catalina and APFS, there's really no need for anti-virus software. The system files are stored on a read-only partition. Whatever malware users encounter are probably installed by the users themselves. These are trojans, not viruses. No anti-virus can protect users from themselves. Running anti-virus software will only eat CPU cycles and RAM because of the background processes they run.

Sorry for the massive screen captures. These are what I have in those folders you mentioned.

Ok, let me uninstall the Norton, have a reboot without chrome loading, and wait for MRT to process whatever it needs to process to see if it can stop.

Macs can get viruses, but do Macs need antivirus software?

Wondering if you need antivirus for Mac? Macs can get viruses and there are protections in macOS to keep you safe - but it's wise to extend the protection.

I see, I spent $60 USD on the annual subscription lol

I only see a few items...

Adobe stuff.
Logitech thing.
UAD thing.
Malwarebytes stuff.
Symantec stuff.

Ok, so, I uninstalled norton, quit google chrome, rebooted. Now I wait for the MRT to process?

Yeah. See if it still runs wild...

 

[singyuk]

Yes, still.

 

[UtterDisbelief]

Yes, still.

Where did you get your copy of Catalina from?

 

[pastrychef]

Yes, still.

Did you also remove Malwarebytes?

Check the previously listed folders to see if the files are gone.
