Hello. My brother's Windows 10 PC is infected with the Trojan.BitCoinMiner.Generic trojan. We both knew it was from a game copy he downloaded from a sketchy website, so we deleted it, and the previous instance of the trojan succeessfully. However, it literally crippled vital parts of his Windows installation, like Windows Update. He was able to fix this without reinstalling by upgrading from build 2004 to 20H2.
1 month later, and suddenly he cannot install updates ("Something went wrong. Try to reopen Settings later."), he cannot download apps from Windows Store (I don't know how, but this Store app is useful and not available as an exe file), Safe Mode sessions are corrupted and he cannot enable the Administrator account no matter what.
Following the steps from this similar post here, we ran a Malwarebytes scan, which quarantined and removed 7 detections of the trojan in various places. Then, we ran a scan using AdwCleaner and rebooted. Finally, we ran Farbar Recovery Scan Tool.
However, as the scripts and log files there were for a completely different Windows installation, I have attached the log files from his PC to see what can be done.
Thank you in advance.
