Sup fellas

I think I might have a little virus, but I'm not sure. A couple of days ago weird things started happening to my pc. It all started with google chrome tabs closing when clicking on them. This issue had been going on for about a week. Yesterday things changed a bit though: sometimes mouse clicks don't register, but only on some parts of the screen while other buttons work just fine so I highly doubt there's an issue with the mouse.

There's also the issue of an extremely high (80-95%) cpu-usage while on the desktop running nothing at all except the task manager. I can clearly hear my cpu and gpu fans revving up to almost max rpm, so I think my pc might be linked to a botnet for bitcoin-mining or something like that. I ran a quick and a full scan with the latest version of malewarebytes, which seemed to have solved the issue after detecting and removing about 7 suspicious files. However, I had the exact same thing when I booted up just now. Is this a virus, and if so, what is the best (free) way to get rid of it, or is it something else?

Regards,
Cheeki.

Download Kaspersky Rescue Disk 10 (KRD) and burn it to a CD, boot to CD and run a scan in Kaspersky Live CD OS, make sure you updates definitions in Kaspersky. Beside Malwarebytes, run different adware/malware removal and see if it helps. A few tools here http://www.bleepingcomputer.com/download/windows/

If it seems to be a virus and you think its a virus, then its probably a virus.

I second supasieu's post, and if that doesn't work, you may need to reinstall Windows

I'd say just to reinstall windows. Nothing runs as good as a fresh install of windows

Or, if you don't want to take the plunge, install Ubuntu on a CD and select Try Ubuntu at the installation screen. This will start Ubuntu without installing it, and if the mouse&keyboard work good here, you need to install Windows again
