Vista machine; only firewall is Windows (disabled); no other software firewalls; originally went to AVG free 8.0 but could not get updates; removed AVG with Windows add/remove. Installed Avast per pdf instructions except removed outlook feature.
Now cannot register from install side since required access through Avast. Got Key directly with another PC since Avast must be off to access internet. When Avast active - no internet access.
Avast 4.8 from site.
Thanks, Bob
