Memory Usage Windows Defender

In Task Manager I can see that MsMpEng.exe is consuming a lot of memory,
both physical and Virtual Memory (more than 60 MB of the latter). I've
learned that this process is related to Windows Defender (am I right?).
It is my feeling that this slows down my computer noticeable. I am afraid of
disabling this service for obvious reasons, and if change its status from
"automatic" to "manual", I get a warning from Windows. I am protected by
Avast! AV and IObit Security, which use, too, a great lot of memory.
Please, comment on the questions implicit in this message.

Thank you very much,
Humpty

And how much memory is installed on your PC?
Does Iobit Security run in the background, or is it a program you have to
run?
And assuming you have the free version, you could in any case uninstall it
to see what difference that makes.

1) Physical memory is 512 MB.
2) IObit Security runs in the background. It consumes a small amount of VM
as compared to Windows Defender, so it does not bother me.
3) I uninstalled and then reinstalled IObit Security and didn't feel any
difference.
4) The most noticeable slowing down of the computer performance, is when
Windows Automatic Update is downloading updates. Also, when Avast! is
actualizing its database. But I suppose that this is off topic.
Thank you,
Humpty
