Suddenly my pc disk started using 100% and the pc was hardly responding.
I started to disable services and the problem ended for a while.
When looking at the names of the services more carefully, I noticed that they are copies of windows services but with a _ followed by some letters and numbers.
If I enter the registry and deactivate them, in the next reboot all the services change those letters and numbers but they continue working.
If I stop them manually after a while they start working one by one.
If I look for them with the antivirus it doesn't recognize it as such.
