Hello,
I have removed some malware located in
C:\ProgramData\Microsoft\SystemService
It was running an executable called systemservice.exe through a script located in the same folder systemservice.cmd.
I detected this because a cmd.exe screen was launched from time to time in my system, I tracked that path by recording a video of my desktop and pausing it at the exact frame the command prompt popped up. It was (and is) really fast.
The problem is that the mechanism running that malware is still active and tries to run systemservice.cmd so I still see the windows popping up, a few seconds after I log in and then it shows up from time to time.
I tried to see if there is any task scheduled for running this, but I can't see were is the source of the problem. Windows defender doesn't detect anything wrong.
This is the hijackthis log:
