Hello, a fellow new member here.
 
A few days ago I had been installing heaps of stuff on my computer. Games, videos etc.
 
The next day I log on to my computer, a new cmd window pops up. I've added the photo for you guys to check it out. My computer's CPU fan began to go crazy and when I checked my process, it says that "vshost" was using all the CPU, even though the new window shows as "svchost" I've checked previous posts about svchost but no one seems to have the process named vshost. Whenever I kill the process from the task manager, it restarts again trying to get back up to %100. The only way to kill it seems by closing it from the cmd window but I'm still concerned.
 
I've used ComboFix, RogueKiller, CCleaner and TDSS Killer but the window still pops up
 
Please help ._.
 
Extra, probably useful help:
1) The Miner can't mine my GPU because my computer's language is Turkish, which changes the GPU's main name(?)
2) I notice a sound of trying to press something when it shows "Welcome". This is the same sound when pressing any letter on the keyboard when waiting for "Welcome". I guess that this shows it opens as user status(?)

Since you ran Combofix...

 

Please follow the instructions in THIS GUIDE starting at Step 6. If you cannot complete a step, skip it and continue.

Once the proper logs are created, then make a NEW TOPIC and post it HERE. Please include a description of your computer issues, what you have done to resolve them, and a link to this topic.

If you can produce at least some of the logs, then please create the new topic and explain what happens when you try to create the log(s) that you couldn't get. If you cannot produce any of the logs, then still post the topic and explain that you followed the Prep. Guide, were unable to create the logs, and describe what happens when you try to create the logs.

It would be helpful if you post a note here once you have completed the steps in the guide and have started your topic in malware removal. Good luck and be patient.

If HelpBot replies to your topic, PLEASE follow Step One so it will report your topic to the team members.

It seems like I found the problem. Hoping that other users who have the same problem as I had, this is the "guide"

 

It's actually pretty extraordinary. Why? Because it isn't a virus. It's a program that  "mines" the GPU and CPU and somehow turns it into money...

Yes, I said MONEY. Did a little search on "Bitcoin mining virus" and I found out that people can actually gain a profit with this type of trick. (Changing the console name to important files for example...)

 

Where did I find the self-opening program? This is my story:

After trying nearly every free anti-virus program and my own McAfee Security System and then failed, I began searching manually. I was in program files when I noticed a new folder, unusually named with a long code (32 digits) of numbers and letters. File named: 64670bfb4cb1da1d12f46b408026f014

 

I checked the folder and guess what? There it said; folders for kernals and miners, plus the console and process interface dll, also including the vshost. Which, I couldn't find when searching. After deleting the folder itself, I rebooted the computer and the console didn't appear. (Thankfully)

 

Though I still thank the admin, moderators and helpers on this site as their posts really helped me finding the problem. So umm, thanks!

 

Note: I compressed the program file into a .rar. (Don't worry, as long as you don't execute the vshost.exe, it won't begin mining :3) Maybe anyone who knows Bitcoin mining might find out how it actually does it.
