Can I change the devices activated with my Avast Ultimate (Multi-Device) subscription?
What is the difference between Avast Ultimate (Multi-Device) and Avast Ultimate?
Both subscription types offer all-in-one privacy, performance and security, and include the following products:
The number of devices and platforms you can activate varies according to your chosen subscription. Avast Ultimate (Multi-Device) allows you to activate up to 10 devices simultaneously and use your subscription on Windows, Mac, Android, and iOS. Avast Ultimate allows you to activate your subscription on 1 Windows PC.
Can I use the products included in my Avast Ultimate subscription on different Windows PCs?
Can I activate every product included in my Avast Ultimate (Multi-Device) subscription?
Yes. You can choose to activate all or just some of the products included in Avast Ultimate (Multi-Device). You can also choose to activate the same product multiple times on different devices.
However, an Avast Ultimate (Multi-Device) subscription cannot be used on more than 10 devices simultaneously. If you are already using your subscription on 10 devices, you can activate additional products on any of your currently activated devices, but you cannot add additional devices.
NOTE: If your subscription is already activated on 10 devices, you can uninstall Avast Ultimate (Multi-Device) from a currently activated device and then activate your subscription on a new device.
