Thank you, folks.
Norton c'est dans la dustbin.
Dumped Norton from my desktop, now run AVG ......AND it found a bug that Norton appears to have missed on its first full system scan (which it now does every 24 hours (as did Norton)). My machine runs a darned site faster, too.
Was already running AdAware SE Personal. Can that be set to run automatically?
I THINK I'm happy with the firewall(s) as they are all configured through my DSL modem and my router.
