Laptop high memory usage problem?

[Irateweek491]

I just recently installed malwarebytes and avast antivirus as I needed some computer protection and now everything has been using much higher memory.

Like for example browsing the web on any web browser (80mb per tab)

and svchost.exe (70mb)

and even windows explorer (45mb)

and other random things

Is this normal because my laptop is roaring due to this

The programs themselves are not using high memory and when I had the free Norton trial things weren't like this so its not a con of using a antivirus in general.

This literally started after the installation of one of these programs.
OK so i noticed that even with the anti virus in off mode things are the same.

everything including the CPU jump to very high percentages (like 70-80%) when i open something as simple as a browser

When opening Google chrome, multiple Google chrome task (like 3-4) are running when i am only running one single tab

25% in itself is fine but its at start up where nothing is running

is the svchost.exe thing temporary because i haven't seen it before which is why it has been concerning me
