Bitcoin Miner virus

Hello, everyone.

 

As the title suggests I've caught up one of these. They're the ones that utilize your GPU at almost 100% when the computer is idle to mine for coins for someone else over the internet. I've gotten not too small a number of these up until this point and always used Malwarebytes to clean them up quite effectively (I believe the category was something along the lines of Heuristics/Shuriken). Not this time, though. Malwarebytes (latest stable version 1.75 + latest virus definitions) seems to pick up nothing - it would usually detect the culprit file, its memory process and a registry key, but this time around it doesn't detect anything ("No malicious items were detected"). I can see the process of the file in Task Manager (its name is gog.exe (32 bit)) and that it also has a startup entry with the same name. I also right-click on the file and choose "Open file location" and see it's been nested under Appdata/Roaming. How do I effectively remove it? I can probably delete it manually but how can I be sure it won't get back, how can I be sure it doesn't have a back-up file somewhere else? It's quite a mystery to me why Malwarebytes won't detect and delete it - never happened before...

Sorry I'm replying so late, but I actually managed to get rid of it by using Emsisoft's Emergency Kit. It contained a portable scanner which removed the bitcoin miner.

 

I'm really surprised Malwarebytes couldn't detect it. In all my previous run-ins with those miners it'd usually eat them for breakfast. But, I'll definitely continue on using Malwarebytes - it has performed quite well so far and one minor hick-up such as this one doesn't mean anything. :)
