I keep getting this message Security Essentials detected a potential threat on your PC. click clean PC to remove
I do this but it keeps repeating message. The threat is Adware win32/Price Gong. How can I remove it for good
Try using a different program - Malwarebytes (the free version) would be my choice. The chances are that it will be found but not removed until you restart the system, something that Malwarebytes will advise you to do following the scan.
