While others have mentioned ways to protect your PC, they aren't
protecting your data...   Use a VPN back to a trusted machine to tunnel
all your traffic encrypted across that public access point, or use
secure protocols like SSL for both incoming and outgoing email, chat
etc...  You can use SSH to tunnel some of these too if your preferred
provider doesn't provide SSL enabled options.

Remember that anyone sitting between you and the internet can watch
everything you do as it goes by unless it's using SSL or equiv.

While I'm not a big Steve Gibson fan, there are some earlier Security
Now podcasts that do a decent job of explaining the problem and point
out some solutions - worth listening to...
