Hi there - I've been running a second-hand machine for a few months and continually hear a "ca-ching"/cash register sound effect that occurs periodically.
I suspect this is some form of a cryptocurrency miner running as a background process, maybe even in my Nvidia GPU - again, the machine is used.
In addition, I think this malware is changing or disabling my MalwareBytes installation, which fails due to a corrupted DLL file sometime after downloading and running successfully, usually after a couple days.
I no longer trust results from MB and it looks like it scans incompletely due to some modification.
I re-downloaded and ran MB, ADW (which had an interrupted automatic restart after executing), and FarBar and have attached logs.
I suspect my Windows 10 copy that came with the machine is a pirated version that may have some form of backdoor or root-kit, so I'm posting more for visibility of this issue rather than a fix, but wanted to see if there's anything I can do before re-formatting my drives.
