Product manual

For example, you have a Program rule for the Symantec
pcAnywhere application that blocks the use of the
application with any other computer. You add another
rule for the same application that allows its use with
a specific computer. You then move the new rule before
the original rule in the program rule list. Norton
Internet Security processes the new rule first and lets
you use Symantec pcAnywhere with that specific
computer. It then processes the original rule and
prevents its use with any other computer.
