You may still be wondering…

Can I change the devices activated with my Avast Ultimate (Multi-Device) subscription?

Yes. If you no longer want to use an activated device, first uninstall all products linked to your Avast Ultimate subscription from the original device. You can then install and activate your chosen products on an alternative device.

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:

Avast Premium Security
Avast Cleanup
Avast SecureLine VPN
Avast Passwords

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?

No. An Avast Ultimate subscription can only be used on one PC, even if you do not install and activate all of the available products. If you wish to use your subscription on more than one device, we recommend purchasing an Avast Ultimate (Multi-Device) subscription, which can be activated on up to 10 devices simultaneously and is additionally valid on multiple platforms.

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.
