As of the last few days windows defender will not open or start up and has turned off spyware and virus protection. In the bottom corner of the screen is a flag saying i have 2 PC issues to be solved, which is turning on virus and spyware protection. When i click on it to turn them on an error message appears with the the error code 0x80073afc. I have searched through various threads on whirlpool and several other sites but am unable to find any resolution to this problem. If anyone knows of a solution or could help out with fixing this problem it would be greatly appreciated.
