Is my account have a free 30 days before I cancel? How do I uninstall Advast from my computer?
What have you tried ?
It should uninstall in the same way as other installed programs Control Panel > Programs > Uninstall a program. Then it is a case of selecting your Avast Installation and choosing Uninstall.
Whilst I don't use Avast One it should be the same as for Avast Antivirus.
