High amount of memory in use?!?

[Juu Nii]

Hello. So, I looked in to my task manager and it showed that 88% of my memory is in use. No application seems to go over 100 MBs tho. What seems to be the problem and is there a solution for this? So. This is what it looks like. Sorry for the language btw. I hope you can still read it.

Here are my specs:
Mobo: AsRock Fatal1ty B150 Gaming K4
CPU: Intel Skylake i5-6500 LGA1151 Quad Core @ 3,2GHz 6MB Cache
RAM: Kingston 8GB(2x4GB) HyperX Fury DDR4 2133 MHz
GPU: Asus ROG STRIX AMD Radeon RX 480 OC 8GB
OS: Windows 10 Home, Finnish
Storage: Seagate 1TB Barracuda, 3.5", Sata3, 7200rpm and some random 2TB HDD from my old Asus PC.

The computer is fairly new and I don't have installed almost anything on it.
I found this out while playing BeamNG.drive and it notified that over 80% of the memory is in use.

Perhaps this is applicable to your issue? http://www.gadgetsupersite.com/antimalware-service-executable-msmpeng-exe-fixed/

Or this

Alright. I did the things said in the first link. [strike]Antimalware service executable calmed down to 37 MBs[/strike]. But it still doesnt explain why in the hell is 8GBs of RAM eaten by something. Oh. And now there's "System and packaged memory" taking 93 MBs of memory. I'll install Malwarebytes now and see what happens.

I scanned the computer with malwarebytes. It catched 3 viruses. I deleted them. The problem still is here. I am now install Avast as one of the links provided by you said that Antimalware executable will stop doing its business when there's an another anti-virus in place.

This isn't really a huge problem as I don't think my performance is any worse but it would still be nice to get fixed. As installing Avast didnt help either. There's something that Windows isn't telling me. 100MBs of 8GBs isn't really all that much... Running CCleaner atm.

UPDATE. Ran CCleaner cleaner and registry multiple times. Fixed all the issues. But still RAM usage is high.

 

[Juu Nii]

Okay. I disabled superfetch under Service Host and the ram usage of it dropped to 4 MBs. But I still have 88% of my RAM used...

Used Rammap.exe to clear out active memory, standby memory etc. Memory usage down to 79% now.

That still seems like you memory usage is still somewhat high. I'm running win 7 with SQL Server and Visual Studio 2015 (with a couple browser windows, etc...) and I'm only consuming 6gb of memory. Do you have alot of applications running? How many icons do you have down in the task bar to the left of the clock? You might want to run MSCONFIG and see if there are services or items in startup that you dont want to run when your PC starts. Be careful though to know what you are disabling.
Furthermore, and this is just my opinion, 8GB is about the bare minimum these days. If you can afford it get 2 more sticks of 4GB ram (16gb total) and you'll have a much better experience.

 

[Juu Nii]

Alright. It is down to 30% now. I don't know what it was but it fixed it.

I made an another post about this and have this figured. I had Killer Ethernet suite installed which for some reason stacked up the RAM usage when downloading stuff.
