So far I no longer get any automatic opening of CMD windows, Malwarebytes along with ADW cleaner and hitam pro as well as windows malicious software removal tool show nothing anymore. I have done more scans now including rootkits and nothig pops up.
I watched the process names and inspected the "C:" drive and found no suspicious folders or anything, So far it's responding good. My only real concern apart from the egguard persistent registry key was something that looked like a miner in the processess list called "zminer" but has been removed in the process of the instructions I followed.
If anything else comes up within the week I'll post here again, Thanks a lot for the help!
