Windows 10: Problem with explorer.exe

Hi,

I recently bought a new PC, assembled personally, after installing and configuring windows, installed the motherboard and vga drivers, antivirus and steam with some games, I realized the following day of a strange behavior of the process "windows explorer" (explorer.exe ), basically what happens is that the process, after a short time since the restart, starts to use constantly 17-18% of the CPU and to increase the consumption of ram.

For example, after 5 minutes it is already occupying 250Mb, after 10 hours it occupies 3.5Gb, and continues to grow without ever stopping.

The problem reoccurs in the same way even after a clean boot with all services and applications started automatically disabled, same as doing a boot in safe mode.

Performed complete scans with: bitdefender antivirus pro, malwarbytes, wipersoft. No threats found and nothing has changed.

Executed memtest successfully without errors

There have never been any blue screens, freezes or crashes of any kind, even during intense gaming sessions

Info pc:

windows 10 pro 64bit updated to 26/01/2019 - version: 10.0.17763 build 17763 original and activated

cpu: Intel i7-9700k - mb: Gigabyte Z390 Aorus pro wifi-cf rev1.0 - vga: Gainward rtx 2080 phoenix GS - Ram: 2x16Gb ddr4 vengeance led 3000Mhz - primary SSD: samsung 970 evo NVMe M.2 500Gb - secondary SSD : 2x480Gb toshiba TR200 Raid 0 - PSU: thermaltake toughpower grand rgb 850W - Corsair H60 liquid cooler




here is a sample image, while the PC is not performing any operation and there are no open programs.

at the moment I do not know how to proceed, and I would like to avoid formatting and complete reinstalling windows, can you help me?

If additional information is needed I am available to provide it

Thanks, Daniel

How can I remove this virus remnant?

I was also going to suggest Autoruns.

Check to make sure it isn't attaching itself to explorer. It should be the 3rd thing listed in Autoruns, the listing for the Shell. It should just be Explorer.exe. If it is anything else, that might be your problem.

That seems to be an attempt at Option 2 in the tutorial, which requires you to
a. Boot to a command prompt (Did you?)
b. You then seem to be mixing steps 3,4 and 5, thus your command is incorrect.

I suggest Option 1 is easier.

If you still have problems, please repost listing each specific step and saying which option from the tutorial you are using. Thanks.
