So long Avast! It wasn't wonderful knowing you...
It should be mentioned, you need to create a free account with Bitdefender before 30 days go by.
I've heard from a few people who didn't activate it that way, and it worked for 30 days, and then everything looked "scary" and they wondered if they had to "purchase protection," just like it didn't say to do. It's free protection! Don't buy stuff!
Ok, I'm done.
Just, activate it.
