Keyboard automatically presses the ESC key again and again. What can I do?

I have been a few days the problem that keeps pressing the Esc key on my laptop. I have already tried the key to clean, the drivers to uninstall, new drivers to install, Unfortunately, all unsuccessful, A virus program, I have already gone through (Kaspersky lab) has also found no virus. I do not know how to continue.

Just do not press the button BROO
