After clearing up an infected computer the keyboard (USB Logitech)stopped working. Keyboard works in Safe Mode only. Have tried the following: uninstalling keyboard devices in Device Manager and restarting (get the yellow exclamation mark by HID keyboard in Device Manager (error code 38 previous driver still in memory, two keyboards show up both say this)Also tried reinstalling software that came with keyboard and restarting, plugging in another keyboard and the same problem occurs so I know it's not the keyboard (keyboard works on another computer), changing to different USB ports. Got it working for a short time (an hour or 2) but then it stopped again.
Any suggestions
