Hello agarcia694,
Welcome to the HP Forums! I hope you enjoy your experience!
I apologize that you are unable to install AVG Internet Security. I will do my best to help you out! However, I first require the following information
1. The computer's model number. If you require assistance locating this information, please reference this website: Locating the Model Number of the Computer
2. The computer's operating system. If you require assistance locating this information, please reference this website to determine your Windows operating system.
If you have an older CD, then the solution would likely be to buy a newer version. This will allow you to install it on a more recent operating system.
Please respond as soon as possible. Thanks for choosing the HP Forums. Have a great day!
Mario
