Does it behave like this all the time or just at specific moments?

I find on my Windows system it's only doing things when specific actions are happening.

Right now the antimalware executable process is using 196.4 MB of memory and 0% CPU for me as I type this.

When I download an executable from the Internet and run it, the CPU usage spikes to 8-10% briefly and the RAM usage goes up by 30MB or so.

I have a much higher-end CPU than that, 6 cores 12 threads (AMD Ryzen 5600X3D)

In my experience the executable is pretty much doing nothing unless I'm opening up an exe that's trying to elevate privileges or if it's doing an active periodic scan.
