Hello Sudhanshu,
This isn't the expected behavior.
Let us check the status after performing a re-installation using remover tools.
Run AVG remover tool followed by Clear tool as mentioned in this (article).
NOTE: If there are no AVG program found, click on "Run Anyway" to proceed with the removal.
Install AVG Internet Security - Unlimited Devices as mentioned (here).
Keep us informed about the status.
AVG Antivirus service Stops abruptly, each time i have to start it manually in task manager and again after few seconds or sometimes few minutes it stops again. Although it was running fine after installation.
In windows event viewer there is a service avgstmxp which is also stopped and shows -
"The avgStmXP service failed to start due to the following error:
The specified procedure could not be found."
Wow, that's great, Sudhanshu.
Thank you for sharing this with us and we appreciate your efforts.
Have a great day!
Problem solved after repairing AVG from ControlPanel->Program & features. Thank you
