Good afternoon, I noticed that for 2 hours of work in the cache 8 gb, although I did not use only the browser(Chrome) and Telegram, no other applications that could take up this space.
I learned about RamMap application in the discussion of another issue and decided to install it to see what is in the cache, I installed it from here ( https://learn.microsoft.com/ru-ru/sysinternals/downloads/rammap )
In the end it doesn't show what is in it, although on the main page in the item "Mapped File" it seems to show the real volume.
Can you somehow help me to see what is in the cache?
I will be very grateful for the answer
Screenshots attached

Sorry, I don't really understand how this is supposed to help me in my situation.

What exactly is your perceived issue?
HarimMZ said:
Could you please explain it in a simpler way? The whole problem is that I can't understand what is in the cached memory and why it is different every day, although the applications used are always the same.

Windows uses free ram for file system caching. This is normal operation.
If some process will require additional ram and there's no free ram available, then cached ram will be released for this process.

Unused ram = wasted ram. You want it all to be used.

I'm not against caching and I don't dream of disabling it on my computer.

The whole purpose of creating my topic here is to understand why the cache is abnormally different on different days, even though the use of applications is the same, and I simply do not have large files of 6-8gb on my computer, but the system still manages to read/write something on this volume.

And I'm afraid that it may be the work of some virus, but all checks of the computer showed that there is nothing on it, but I do not know how much you can believe it, I want to make sure that it is really the work of the system and not a virus and forget it

No.

Process Explorer will simply show what is running on the system.

"I want to make sure that it is really the work of the system and not a virus and forget it"

What is in the cache is the work of the system (not a virus) and is not understandable.

Time to forget it.

How sure are you that it may not be a virus that unloads some files from my computer?(I can roughly see this possibility of a virus causing the cache to be like this).

NOT applications.

Read through that link. 256KB chunks of data.

This is nothing recognizable. It won't say "GTA V" or "Notepad". Instead, it might be a particular chunk of a jpg.

I just saw a video of a person running a 1gb video from disk and then he had about 1gb of cache added.
Later he showed with the help of RamMap that the same video was displayed in the "Mapped File" tab, that's why I wrote about previously launched applications

So then you have your answer.

Do you see a line in there labeled "I AM A VIRUS!"
Click to expand...
Lmao, ofc no :D
But if you open the screenshot from my first post in this thread you will see that the cache is 8gb, and in the lists of files the heaviest thing is 300mb. From not knowing what the system caches and the fear of viruses appeared :(

Right.
It just shows "Mapped file".

It says absolutely nothing about the contents of that data, virus or otherwise.

I'm not saying I'm getting "virus.exe" somewhere.

You detect a virus by use of various AV and malware tools.
Not by looking at random data in the cache.

If you're still not satisfied, full wipe and reinstall. OS and everything else.

Are you suggesting erasing OC completely to compare whether the cache will accumulate as it does now?
I thought about it, but I would have to install all the drivers again, enter in accounts that can not be synchronized. I was also suggested to disable SysMain and see if it has any effect on it, I think if after disabling the cache will behave like that, then I will have to really erase everything from disks and install OC again
About AV, I've tried a bunch of different tools, even livecd, but nothing has turned up

No.

I'm saying a couple of things:

1. If you still think you have a "virus", after much effort with various AV tools, then maybe a full wipe and reinstall is needed.
2. Stop worrying about what may or may not be in the cache at any particular moment, or the size of it.
3. Disabling the cache would have no effect on a virus. Leave it alone.

No one told me on any forum that they had not observed this in their own country (maybe they just don’t look there :D) and, in particular, because of this, I got the idea that it could be a virus.
Although, if you think logically, I tried 5 different AV and livecd from Kaspersky, which reduces the possibility of the virus to a minimum.
If the same thing happens on a completely new OS, it looks like the problem will really be in the system itself.
Maybe @Ralston18 can say something new

Again, and for the last time - I'm not seeing a problem that needs to be fixed.

@HarimMZ

That YT video is 23 minutes long , low quality, and overall not a video I am willing to fully watch even if I could understand it. Which I cannot.

Took a quick look to see what I could work out. Not much.

As near as I could understand there was 4 GB present and 1 GB was added somewhere (via file 1.dat ?) and he discovered that the cache or something increased to 5 GB.

On face value I question both the methodology and the presented results.

If you believe, based on that video, that a virus is hiding in your system's cache then you have no choice but to follow through with a full system wipe and reinstall.

What I believe (also) is that there is no problem and nothing that needs to be fixed .
And that is not something new.

Per @USAFRet

"Stop worrying about what may or may not be in the cache at any particular moment, or the size of it."
