System32 takes too much space (300gb)

Hello, how are you all, I found that a lof of people have same problem, but i didn't found any concrete steps to resolve the problem (found that people have this problem with indexing, and hidden files).

My situation is next:

Here is the picture of system32 size: Screenshot 1 — Postimages

Here the picture of folders and files beside new files that came up: Screenshot 2 — Postimages

And here are the new files, that all have same timestamp date 5/18/2023, and they are listed on alphabetical order from 0-9 and then from a-z: Screenshot 3 — Postimages , Screenshot 4 — Postimages

There is too much of these new files, when I try to select them I and check their properties the system freeze in intervals.

What should I do, reboot the system? Delete these new files (probably shouldn't do this)? Or something else?

 

System32 takes too much space (300gb)

The 1074 KB executables can be deleted.

They're created by a MSI service whose executable (OmApSvcBroker.exe) got compromised recently.

See:

• (Urgent!!) system 32 folder suddenly shows many gibberish .exe files - Microsoft Community
  

• VirusTotal - File - 6725494dce5cd19e3e690cf9066d0a4b3463d92ee2bd2430c3c56fdad34f26da
  

In that VT link, a poster commented:

"A malware, which generates additional files under random names in .exe file format. Came from MSI's Center, probably got breached in that day. It would run up to two processes from created files to create even more files - in the end, fills up hard-drive and Windows\System32 folder with 1,074 kb files. The signature is valid, belongs to "micro-star international co., ltd.", which is used to bypass detections."

Stop OmApSvcBroker.exe and delete it:

From admin Command Prompt, run:

• schtasks.exe /delete /TN "\OmApSvcBroker" /f
  

Start Windows in Safe mode and delete OmApSvcBroker.exe
