Hello Pritesh,
I'm sorry but I could not see the screenshot so I request you to attach the AVG Antivirus virus definition update failed error message again to assist you further. You can post the screenshot here in your topic. Click on 'Answer' & then click on the 'Image' [mountain symbol] & follow the instructions.
Best regards,
Alok.
