Avast shows two devices in "My Devices" but I only have one!

Under “My Devices” it lists two devices: “PAUL” and “STUDIO” but currently all I have is my desktop PC (PAUL). My previous PC was named “STUDIO” so I’m wondering if for some reason Avast still thinks that it still exists on my account. Is there any way to correct this or is it no big deal and I should just leave it alone?

Unless you delete old installations/devices they would probably remain, but may well show that they haven’t ben updated or communication for some time.

So you can delete the old Studio device.
