When avast free expire, will the viruses in the “Move To Chest” come out and destroy my computer or will the viruses be gone too?
You just register again, it will give you a warning that it is about to expire, your virus would stay in chest, if you didn’t re register you would just have outdated Avast, it’s not going to attack your computer for letting expire ;D
How do I register?
What is your system and version of avast ?
There also shouldn’t be anything in the chest to “come out and destroy” anything. You should clean out anything in the chest older than a couple of weeks if everything has been working fine since they were put in there. By clean out I mean delete, not restore.
Their are two ways to do this see link for information https://support.avast.com/index.php?_m=knowledgebase&_a=viewarticle&kbarticleid=459
