I regard none of these as useful. They are not solutions: they are, at best, rationalizations for a bad decision on Symantec's part.
When, if ever, was giving users local admin rights on their computers in a business setting a remotely good idea?
I want my users to get notified and I want them to get notified pretty promptly if the defintions are outdated but I don't want the notice to keep popping up every 60 seconds because then I will be foreced to kill them outright.
The documented way this alert was just fine and allowed not only all the options the now-crippled implemenation does, but also allowed additional options that it no longer has.
