@DonZ63,
I highly doubt that you'll convince anyone here to switch to Symantec.
Most of us here originally left Norton because it was using more of the computer than the user.
Despite the fact that the current versions have greatly improved, why would any one
in their right mind give up something that's free and, is doing the job, for something that costs money.
If you're using the paid version od avast!, I think it also does more for less so it's still the
better choice.
Since you seem to be happy with the change that you've made, enjoy it but, don't look for or expect
to find converts on this forum.
