I'm experiencing very strange behavior. Once every 15/20 mins, something takes over the control of inputs and starts clicking, typing meaningful phrases (that I've typed some time ago) - e.g if I happen to be inside a textbox, it types stuff into the textbox.
It's really annoying, some kind of virus or maleware. Did you see anything like that? I have antivirus software running all the time, just done a maleware scan and all is reported 'fine'.
