I have a problem which I remember from long ago but I do not remember the solution. The thing is that sometimes, quite randomly, the keyboard does not do what it should. For example, when pressing the letter "e" with the cursor in notepad, it opens an open menu instead of writing an "e" in notepad. The same with many other letters which instead of getting written are associated to particular actions.
Does any of you have any suggestion to solve this?
Might it have to do with a virus? Real time avast monitor is not warning anything currently.
