I’m on Mac OS X 10.7.5, just installed Avast Mac Security 2015 (ver. 10.8), signed up with an account, but when I click on the Account tab, the loading moving icon just keep saying it’s loading. Been like this for over 3 minutes now. I’m not on Firewall, or VPN…
Will it be any setting issues that I’m no aware of?
Thanks for your kind attention in advance 
Having the same issue, and avast will not update either. Yet when I log into my account online, it says everything is ok. But when i open the application on MAC it wont connect to update. It also says the program is not secured.
Do you or did you have any other security (related) software installed ?
Yeah I have Little Snitch network monitor installed, however Avast has been set to allow any incoming / outgoing connection
One Japanese user reported the same issue.
Uninstall and reinstall does not solve the issue. VPS update is working fine though.
Follow-ups;
The issue reported by the Japanese user turned out to be caused by the Mac native firewall.
He/She had unchecked “Allow incoming connection for signed application automatically”; thus it blocked avast automatically.
Allowing incoming connection to “Avast Mac Security.app” resolves the issue.
