Securing Your Computer

Learn what technical protections you can put in place to keep your computer safe.

Thankfully, as more people have become concerned about computer security, the software makers responded by making it easier to set up basic defenses on personal computers. In fact, many personal computers now ship with some basic computer security measures already turned on. In general, your computer should have all updates and patches installed. It should be running current antivirus and anti-malware software. And your computer should have its firewall turned on.

These basic protections will keep you safe from most attacks online. However, do keep in mind that even some of the best technical protections can often be thwarted by a human's bad decisions. Therefore, it's important not only to learn technical protections for your computer, but to learn how to spot and avoid scams and threats online.
