Hello Pradeep,

I apologize for the inconvenience. I would request you to uninstall AVG Antivirus pro and then reinstall it to fix the issue.

1. Device Menu -> Settings -> Apps/Application Manager -> AVG -> Uninstall. 
2. Restart your device once. 
3. Open Google play store app on your device. 
4. Search for AVG Anti-virus. 
5. Locate and install the free version of the app. 
6. Now open the installed app. 
7. Tap on the drawer (3 lines) on top-left of the app and select Login option. 
8. Enter your My Account email address and password. 

Now, the AVG Anti-virus will upgrade to PRO within few minutes. 

If not, please wait for 24 hours and check whether it's upgraded to PRO. I'm sure this information will help you. If you still experiencing the issue, please write back to us. Thank you for the understanding and patience.
