How Do I Get Rid of This Cryptomining Virus?
Okay, so about a few days ago I noticed that exactly at the beginning of every hour, I would get a command prompt console open. Sometimes it would open for a second and then minimize into the background, but sometimes it would stay open and I would see it mining DAG or something from my GPU.
I went into Task Manager and found the app running it (called User.exe) opened its file location (AppData/Local) and deleted two files named User.exe and another named Profile.exe.
I went into Task Scheduler and deleted the schedule that Profile.exe (which is used to launch the command prompt, User.exe) launches every hour.
Should be fine and gone, right? Nope. While I was using my PC, it came back. Re-adds the schedule, and readds the app to AppData/Local.
I download procexp and find User.exe, and see that it uses a launch command (that I couldn’t see in properties or anywhere else) that connects user.exe to 2miners.com, using KAWPOW, uses asia-rvn.2miners.com specifically.
I downloaded Kaspersky, then MalwareBytes, and then used Windows Security when each one did nothing. Kaspersky was the only one that Identified it as a virus, both skipped it and said something about it being ‘impossible’.
I booted Windows in safe mode multiple times and deep scanned the PC, and nothing happened.
I used VirusTotal to search for it, it and give me a 0/48, when I used procexp for it, it gave me 18/48.
I searched through the registry for something but did not find anything.
I see a lot of online solutions basically saying, fresh install, nothing would help, but i can’t. I have TBs of information all integrated into this Windows system, all years old and I have no clue where I got them from, but most of them are for my editing software, for my music production, and for my small coding attempts, so reinstalling Windows is not an option for me.
What do I do? It’s so annoying having to shut it down every hour.Usuario de Reddit
