Computer typing by itself virus or I'm hacked?

[williamlycke]

A few days ago I downloaded a movie torrent and it seems like I got something unwanted with it. First time I've had a problem with torrents so it's a big let down.

Ever since then my computer sometimes types by itself but it also switches windows and pressed all kinds of buttons. When it starts doing that it is impossible to use it. It was worse today than ever before. Anyone know about a fix or at least what it could be? Virus programs doesn't detect anything. Someone said something about it meaning that my computer was hacked and if it is, what could I do?

I have a custom built pc specialized to be good for gaming. All help is appreciated since it's a pain to see the computer in this state

well its been said before download illegal files, get hacked, by backdoor.
Only real solution disconnect internet from computer, backup your date on external drive, kill partitions, reinstall windows.

but it also switches windows and pressed all kinds of buttons.

Someone else is running your system.
Disconnect, wipe, and reinstall.

And change all your passwords..all of them.
