Trying to get any info out of Symantec is useless!! could someone tell me what
6 months Subscription means, does this mean I pay say $50 for NAV and 6 months later I throw it in the bin!

It's rather confusing! All the payware applications mention subscription costs, if anyone can shed some light here I would appreciate it!
Edit: I just had another go at trying to email Symantec for some info but there is no way to email them, you just get sent on a wild goose chase that ends back at the start, so I have given up on them!
