I want to uninstall avg from my pc

Hello Bashiir,
You've reached the AVG community support forum.
We'll certainly look into it and help you. I am sorry to hear the inconvenience you had with uninstalling AVG Antivirus free/ Internet Security due to the password. Based on your words, it seems to be an AVG Interface password which will ask you to enter the password to access the settings and while uninstalling the program.

Since you are not aware of the password, I request you to run a AVG Uninstall tool in safe mode and boot the PC in normal mode and try to uninstall the application. For step by step instructions, please refer to the
article: Using the AVG Uninstall Tool

I hope this clarifies and helps. Feel free to write back if you need any other help! Thank you for your understanding.
