Is there any way to force the Avast to update before a computer can be used. My daughter never updates her antivirus, so I want to force her to wait to use the computer until after the program and definitions are completely up to date.
Is this possible?
Avast chech for updates as soon as it detect connection…
Stream updates comes in evry 5-15 minutes
OK. Is there a way to make the computer unusable until the updates have been completed right after boot?
No, but you can set automatic updates for both program and definitions, and put a password on Avast! so she can not change anything

Not within avast there isn’t - though you could try to find something to delay windows start slightly.

I don’t know if you have your daughter to:
A) logon to her account - during this period avast being for all users would probably be updating before they complete the logon.
B) with this cavalier attitude to security - perhaps you should have your daughter on a limited user account. If for no other reason it can limit damage if she does get infected.
