Can Norton internet security function while internet is on?  

Norton functions while you're connected to the internet. You dont really need to disable it to work online If enabling Norton hinders your onlline capabilities, then you may need to call Norton
(1-800.491.7234) . Some settings may need to be checked. If Norton is disabled, your computer will be exposed to harmful things in the net.

Hi happyever
I was using this but never faced what you talk of, but after scan i had to restart my computer always.
In my view out of all Microsoft security is the best, i had tried most of the free versions, some of them seem to be virus themselves, the paiful part is they say, it removed xxx virus, not others, they can kill uour pc etc etc, buy the registered version for total protection..
Thanks for sharing
Cheers.
God bless you, have a nice day ahead.
