My computer is infected but AV software does not find anything

I still would like to see some of the printscreen i asked for. Just telling us.. Also would like to see the totalvirus url of the scanned file: wlanext.exe

Most cases malware uses powershell or conhost on the first run of infection to get the payload on the machine, and then stops doing those things. So you won't see it constantly running... And then just inserts/hijacks a running process at startup without it running its own.exe file, and you won't even see it.

If it is really an infection, i would do a fresh reinstall.

If you want to figure it really out, i would attach a debugger to all processes, and see if debugger detaches, or getting access violoation on the attached programs..

Also install a firewall that reports on all outgoing traffic, and then only allow processes to access internet you trust. like 70% can be defaultly block.
A free firewall, can be as simple as the malwarebytes firewall control: https://forums.malwarebytes.com/topic/296798-malwarebytes-windows-firewall-control-wfc/ Then when you get a virus/malware, it cannot defaultly connect to the internet.

You mentioned dllhost starts with a command..... Look at dllhost.exe dllhost.exe - What is dllhost.exe?

If you used this computer for banking I would notify the Bank. I also suggest you do a clean install and change all passwords using a known clean computer.

Kaspersky does not find anything...

Normal!

Why are you telling us that Kaspersky doesn't find anything? If you know how to copy and paste any of the results from anti-virus programs you've run, please do so, or ask how to do it.

Avast also does not find anything. What's the purpose of pasting "all is OK"?

Okay, so I found a directory structure with circular references in Firefox profile folder, which cannot be deleted. Inside are files looking like folders with name "https+++you.com." which cannot be entered or deleted.

The structure is located at
C:\Users\User\AppData\Roaming\Mozilla\Firefox\Profiles\<my profile>\storage\archives

I would do a clean install of windows for peace of mind.
