During a regular Ridnacs check I was clearing space on my SDD, and I've discovered a large bitcoin folder with 8 gigs or more, while I've never had Bitcoin. This is apparently a rogue miner on my system that flew under the AV (ESET NOD32) and Malware Bits.
I have had a rogue miner before, about 2 years ago, the MDM.exe (Slaveware, hid itself in cache folders of another application) that also went undetected, I was only able to find it in process monitor after 2 weeks of bad performance. But this one, I am completely unable to detect it, no bad performance. For now I am going to wait and see if the bitcoin folder starts to build itself back up again, and I would like suggestions on where else to look, and what to look for?
