Symantec is usually reliable, and I like software that is backed up by research.
The chat guy in India offered to remote into my computer to give me the latest build from Symantec ... Wonder why they aren't selling that ?
The antivirus package that downloads from Symantec doesn't work, but they do have another build, maybe...
If the firewall isn't set to trust all apps, you'll have to research a zillion OS X apps to find out what is going on.
Someday when it works it'll be pretty goood...
