1. Turn operating system updates on -- Ensure the operating system's automatic updates are turned on. Most operating systems, such as Microsoft Windows and Macintosh, include free automated security updates to protect computers and files from hackers.
2. Install a firewall -- A firewall is the first line of defense against online threats. It monitors the data passed between a computer and the Internet. Of the 70 percent of Americans that believe they have a firewall installed, only 64 percent actually have it enabled.*** If customers already have a firewall, make sure that it is enabled.
