Keep Your Operating System and Browser Up to Date

Operating system updates and upgrades are released often to repair security flaws that are found after the operating system software was first released. Make sure your operating system software (Microsoft® Windows or Macintosh®, for example) is currently supported by its supplier and has the latest security updates. Since new vulnerabilities may be discovered at any time, we recommend that you use an automatic update service.

Updating your browser is also a good idea. The most recent versions of Internet Explorer and Firefox have functionality to warn consumers before going to a reported phishing website, so users are immediately warned of potential threats, even if that site takes several hours to shut down. Visit our Discover Site Security Measures page for details on browser safety and how to download the latest version on your computer.

Use the Most Current Antivirus Software

New viruses pop-up all the time. Make sure your antivirus software uses the latest antivirus signature files. Signature files make it possible for the software to detect viruses. You should be able to download and install updates through the software vendor's Web site. Most antivirus companies offer subscription services to ensure you get the latest updates.

Install a Firewall to Keep Hackers Out

Being connected to the Internet means information continually travels freely to and from your computer. An easy-to-install personal firewall helps you screen out unauthorized communications to your computer and can prevent hackers from gaining access while you're online. This is especially important if you connect to the Internet via a cable modem or a digital subscriber line (DSL) modem.
