Windows 10: Windows Defender questionable RAM usage

So I decided to use built-in Windows Defender and Malwarebytes free as my second opinion scanner, I just would like to make sure that there's nothing wrong with these values of the Windows Defender RAM memory usage, it goes from 120-150MB when in idle mode, I have 16GB of DDR4 ram and it's not representing any problem, but I would just like to know if it's possible to reduce it to like 50-60MB of memory usage or something else, thanks!

Task Manager RAM Usage

My computer is running 64 bit Windows 10 with 6 GB of RAM.

I have been monitoring my memory usage via Task Manager and occasionally download tasklist via the cmd line.

What has been bothering me is that my RAM usage at reboot starts at 34%, and left alone, increases to ~75-80% without running any programs.
(I do have start up programs including McAfee, Dropbox, Seagate console, gadgets, etc.)

When I analyze the tasklist download file via Excel, the total RAM memory usage is approximately 3.1 GB at 79%.
Doing the math, this means there is only 4 GB in use?

I have 2 questions:

1. Does Task Manager list all the RAM usage or is there some background usage that is not shown.?

2. Is there any other way to monitor RAM leakage?

 

RAM usage.

Sorry sir...but can you please answer the question that was asked? Is there a way to find out the Ram usage in a windows phone..

 

Task Manager RAM Usage

I did perform a clean boot and my RAM usage has been steady and below 70%, whereas previously I was topping out at 87%.

Now I am trying to find out what, if anything, I am missing. So far, everything is running that I use frequently.

A little worried about my McAfee antivirus programs running against Windows Defender. Any suggestion??

I also am curious what was causing the RAM leakage, but I guess I will have to reactivate programs incrementally.
