LifeLock stops all intrusionsI wouldn't bet on that. Otherwise, why would they make this claim ...
"If you become a victim of identity theft while a LifeLock member, we'll spend up to $1 million
to hire the necessary lawyers, accountants and investigators to help your recovery."
Norton is an anti-virus, not an anti- ID-theft program ... and like any AV program, doesn't guarantee anything.
You covered your bases as best you can, but there's always a chance "things" will happen.
