"Limit activity to Web surfing only using wireless hotspots. A hotspot is an open wireless network that is available (open) to everyone. An example would be the wireless network at your favorite coffee shop. These networks hook computers into the public Internet -- handy but dangerous. Because wireless hotspots are for open use, they don't provide much protection for your data. When using a wireless hotspot try to limit activity to web surfing only. You should also disable peer-to-peer networking, file sharing, and remote access. Always use a good personal firewall and of course make sure all your software including your operating system (like Windows) is up to date and patched. You should never use hotspots for online banking, bill paying or for making purchases that require you to give out confidential information such as a credit card number."
