The keyboard of my HP mini has suddenly started to act strangely. If I press any key on the asdfg row, I get that letter and the letter diagonally below it: a gives az; s gives sx. The space bar throws a carriage return. I can use an external USB keyboard, but not the netbook keyboard itself.
In addition, windows open randomly - like the opening screen of Windows Media Player.
To me, this all looks like a virus - but running Avast and Malwarebytes only produced a couple of PUP's. Removing them has not changed the behaviour. I also checked for drivers and updated the BIOS from HP's site, but that was no good.
