This is 2 complaints: The first one I resolved myself but am reporting it FWIW...
1) I tried several times to download the free version of Avast Anti-virus, but the Cnet site just sat there. I finally installed the previous version rather than the one being proffered and it downloaded. On installation it auto updated to the current version.
2) I have a copy of Avast Anti-virus on a desktop PC. It is registered and my account shows it as one device, but when I downloaded and installed another version to my laptop, I can not find a link to add another device to my account when registering that copy.
Question: I want to also install a copy to my wife's PC. Does this require a separate account for each device I install Avast to? If so, what is the purpose of a device list on the account page?
