After PC format question!

Hello to the Avast! community.This is my first post in the forum so I’ll try to make it as good as possible.
Well I have just a simple question:
I yesterday purchased my Internet Security license. IF I make a format in my laptop,do I need to purchase a new license,or I’ll just put my license number in the new Avast.exe that I’ll download after the format?
Sorry for my bad English,if I miss something to make the question better,feel free to ask me in the comments.
Thanks in advance,Chris.

You can use the license as long as it is valid.

If you need to download your license again, you can do so through your avast account ( https://my.avast.com )
