Protect yourself

Protect yourself by avoiding credit card transactions while using unencrypted Wi Fi hotspotsandsuch as those offered free in many businesses and restaurants. Sharing is great at home, but it s a liability on public Wi Fi. Considering that you probably don t have password protections on all of your files, literally anyone could browse through your computer. It doesn t take any special skills. When your computer is set to share, it s basically begging for other devices to take its information. If you have a Windows operating system, you can automatically block sharing by choosing the andpublicand network setting. You can also do this manually under Change Advanced Sharing Settings.
