Do you have an AV program and if so have you run a scan lately?
Two days ago my computer starting mis-behaving, it seems to randomly and repeatedly open files. Its favorite was Power cinema so I uninstalled that but its still doing it which makes work impossible.
If it opens something like notepad it also starts writing random gibberish. Sometimes the keyboard stops working.
I have wireless laser desktop 6000 keyboard and mouse combo which I replaced the batteries in yesterday. The keyboard has a built in volume control which also randomly appears on the bottom right hand of the screen even though it is not pressed.
Does anyone know why this is happeneing? What can fix it?
