Check if the keyboard is broken, and after confirming that it is normal, try to delete the driver and install it again.
-
Obviously, it's either a keyboard issue or a PS 2 interface.
-
Reboot, enter CMOS, if the keyboard does not operate normally, it is a problem with the keyboard.
-
Keyboard drivers are a must-have for every system.
So you first consider whether there is something wrong with your system, the yellow circle and the exclamation point are obviously driving the problem. Check the driver first.
Since you can't change the keyboard, it means that the keyboard is fine.
Find someone who understands to help you install the system.

Windows comes with its own driver.,It should be a broken keyboard.,Just change it to a new keyboard!

Hero, I haven't heard of the keyboard virus! I guess your keyboard is broken, or which key of the keyboard is stuck! After the antivirus, the spring is loose again, but it is used by you and stuck on it, and it doesn't work, the easiest way is for you to change this keyboard to try it, is it the same situation?
In the same case, that 100% is a broken keyboard! If it's a notebook, then go into PE to try these buttons, and if there is such a problem, it is not caused by a virus! If it's all right, you can only reinstall the system!

That's definitely not a virus! You go to my computer - control panel - keyboard. Take a look there, if not there, there's something wrong with your keyboard!
And there is no keyboard poison. The suspicious file of the exe you said may have been left by other software! So it's not a virus problem!
Trouble, thanks!
