Not picking up threats

Hello Anthony,
Could you please confirm whether you suspect any files on your PC as infection? If so have you tried to scan the specified file using the AVG program?
Thank you.

My AVG Free Edition isn't picking up potential threats anymore like it used to. I tried uninstalling and reinstalling but it doesn't pick up anything at all even after about five scans....why?
