I share my virus protection with another member of the family, my problem is I had to perform a factory restore on her computer, renamed it and now I can’t share avast with her. I would like to delete or change the previous computer name and add it back under the new name. Is this possible?
Yes it is, just Remove the Device from the Account - (Go to the Device overview page, choose Settings and Delete from account). Install Avast on the new device and pair it to your account.
