wifi question

Saw an item of CBC talking about a woman in her hotel room using the wifi who received a phone call from someone in the hotel bar telling her she had better close her file sharing and get off the wifi right away because he could see all her info including bank accounts, passport info etc which she had on her laptop.  How do you shut off file sharing?  I always use hotel and ship wifi and often they warn you that others could see your stuff.  What do you recommend in order to prevent this problem.
Thanks,

Here is a good article on how to disable it:

Really, your best bet is to just disable file sharing. Hotel networks are often dangerous, and without going to a hassle, your best bet is to just disable it, as I referenced in the link above. Also, just be conscious and don't keep important files on your laptop when using unsafe WiFi connections; keep a USB key or external hard drive for that. That's the easiest way to be safe. :)

The first thing you do is disable resource sharing.  Then install a good personal firewall.  Make sure ALL the local user accounts have passwords.  Keep your operating system and application software up to date with patches.

you never can expect privacy when transmitting your data with an emitter - which is what you do with wi-fi

I wonder why no one has yet written, that by default, file sharing is disabled, so no matter on what type of firewall profile you are (public/private/domain), the ports are closed, no one can come in.
Recommendation: know what you are doing, no more, no less. So if you decide to turn on sharing, know the consequences.

But it seems you haven't changed the defaults, have you? Then there's no need for action.
