I am planning on switching my computer's operating system, so I will have to restore a lot of my programs. But I was wondering if i will be able to reinstall AVG? I dont have the CD because I dowloaded it on the web (i did pay for it). Its a 24 month subscription and i've only had it for 6, so i dont want to lose it.
It is version 9.0814.
I do still have the license number.
