Be cautious about what you do on public Wi-Fi, and use a VPN if possible. Another option is to look for semi-public networks, i.e. ones with passwords that are provided by staff or on printed receipts, like at restaurants or coffee shops. Up-to-date security software is also a must-have to shield you from any malware you might contract from public Wi-Fi.
