|Do you know a better way, genius?|
A great many who post here blame virus for every single inexplicable (to them) bit of computer behaviour - given that most enjoy a rather lacklustre level of experience or expertise in technology, they are often quite mistaken
And, oh yeah - this: "I got the same problem" - - heh - - pretty much meaningless in and of itself. Aside from the fact that most who make that claim are mistaken, you might consider referencing those "same problem" posts by number or link, on the off chance that they might provide useful information.

"I have performed virus scan. No results."
While "no results" seems to justify my argument over yours, only a novice or a fool would rely on the results of a single application (although, true, the two aren't mutually exclusive). I'd suggested you try others - that might have been a better use of your time rather than the pitiful effort you've invested in chastising me
These are 'interesting times' to be running a computer - most inexperienced folks are infected with something but it's seldom the culprit(s) they suspect.
I've never heard of a "keyboard virus" (not in a dozen years of computing, half of that spent here) - my 'guess' is that you've somehow changed the keyboard language layout - - maybe I'm wrong. You might check that, and if not, scan away
