How to use migration assistant

how do I turn off avast to use migration assistant? I’m moving from PC to Apple and have never moved files before.

First, I’m an Avast user and not an Avast Team member.

It isn’t just a case of turning off Avast.
I would suggest that you completely remove Uninstall Avast possibly going as far as

The reason I say this is that the Windows version of Avast isn’t compatible with the iOS operating system, so you don’t want ‘any remnants’. There is an Avast version for iOS so you could install that on your Apple system.

Thanks for the info.

You’re welcome, hopefully it will help in your migration.
