My AVG session has expired recently. How can I get a new serial key for one more year?
when I update ,tell me, can't update. why
In order to receive a new serial key, you will need to purchase a new license for the software. For this purpose, I recommend that you contact the official developers. Also, if you want, you can use the free version of the program that you can find on AVG Download Center.
you can't update it because its an illegal/pirated serial number!
AVG disabled your ability to update because you used one.
If you didn't use that illegal serial number, reinstall AVG then it should work.
