Choose the media type that you want to use an empty USB flash drive or a recordable CD/DVD.
All you need is an uninfected computer with Avast Antivirus 2015 installed and an empty USB flash drive (make sure it is fairly new so that it supports booting) or a blank recordable CD/DVD. You can create the Avast Rescue Disk from any Avast product. To run a virus scan when offline, create an Avast Rescue Disk.
