Unknown infection - unable to fight it


Recommended Posts

Hi, 

I own a desktop computer with Windows 10 64-bit. 

2 days ago, I was casually using my computer (playing Minecraft) when I noticed Google Chrome opened itself, without any intervention from me. I closed it and went back to what I was doing, and it happened again. Worried, I wanted to check if anything malicious was running in the background. I was unable to open task manager. I tried running my antivirus software but it wouldn't. I tried opening Malwarebytes, it wouldn't. Same thing with the 13 Chameleons. I've tried every workaround program from MalwareBytes available, none will run. I can't access Windows Update option (the settings W10 app crashes when I click on the update section), nor the Download folder from the file explorer. None of the Rkill links you provide works (the loading mouse cursor appears, the explorer window from which i'm launching the file freezes from 2 to 3 minutes, and then I get an error message). I can access the web with Firefox but Chrome wont' launch. I can run Minecraft's exe file but not any program that would get me closer to getting rid of the virus. 

I can't reset my computer via the computer panel, since the window freezes when I click any of the options available. I can't access user account options from the Control Panel either. 

The FRST64.exe file won't run, so I can't give you any log.... I tried to be as precise as I could with the limited knowledge I have. 

 

What should I do?
