Internet security for a beginner
I am in the process of selling a desktop computer to a friend who for all intents and purposes is a computer beginner. I will be recommending to her that as soon as she gets on line she subscribes to an anti-virus site, but what about firewalls? If she will only be on a dialup connection, does she need a firewall? I have Zonealarm (free version) on my computer but if I put it on hers I know she is going to be totally confused every time it asks "do you want to allow this etc etc".
Similarly, what do I tell her about the "do you want to download xxxxx and do you want to always trust soandso corporation?" My default answer is No, piss off, if I want you I'll ask for you, but is that a suitable response for newbies? How often will she miss out on something relatively iimportant by always saying no?
I know this is by definition vague, but any hints in the general direction would be appreciated.
