Subscription downgrade

My subscription is currently for 3 devices, but I no longer need that level of protection.  How do I downgrade my subscription to 1 device?

Hello Alicia,

Upon checking your record, we see that you have purchased the license for AVG Internet Security (3 computers) and it expires on 4/4/2016.
You don't have auto renewal active for this license so you have to renew your license manually.
So when this license expires  you can purchase a fresh license for one computer.
If you need any assistance regarding the purchase please contact our sales support via https://support.avg.com/support_sales?l= .
