Hi, we have some troubles with my avast account and related features (device pairing, information update like avast version, VPS version, etc.) so we have to temporarily shut down the service; it means that you still will be able to login&see your account, but probably you will not be able to unpair/pair devices or register your free versions. As soon as we will fix it I let you know. Thank you for your understanding.
Everything should be fine now. Thanks.
