There are some basic precautions you can take when using public Wi-Fi, including:
- Making sure your security updates are up to date
- Avoiding clicking on suspicious pop-up screens prompts
- Looking for secure site padlock icons on the left-hand side of your URL bars
- Turning off file and printer sharing
However, one of the best things you can do to keep your computer safe when using public Wi-Fi is to use a VPN or Virtual Private Network. When you connect to the internet through a VPN, your IP address is hidden and your search traffic is encrypted. Using a VPN keeps your identity and internet use protected from anyone trying to access the information on your computer.
