How to remove Hard Drive Diagnostic

dear greak police,


My computer is suffering from a program called " hardware diagnostic" . I don't know how it got installed. It always prompts about errors in computers that is never present. It tries to convince user to buy the program. It starts while booting the computer.This program also has a system tray icon which shows there is critical error. After sometimes it also turns desktop screen completely black.


I have uploaded the print screen of the error. I will be extremely thankful if you could help me remove it.


Regards,
knight

You system restored to a point before the infection? Any change?
