Protecting your computer is important to keeping the personal, business, and financial information stored on it secure. Fortunately, protecting your computer is simple if you follow the right security guidelines. Using a highly secure password and setting up a verification process makes it difficult for other people or programs to impersonate you and access your information. Using protection software also makes it difficult for hackers, viruses, or malware to get into your computer. In addition to software protection, encryption and compliance with safety principles will contribute to data security when you use the Internet.
Steps
Use security software

- The built-in Windows firewall is just as effective as an antivirus program’s firewall. [2] X Research Source
- Make sure the computer has a network connection when you turn on the firewall so that it is connected.
- If you don’t find that shortcut, type “firewall” in the search bar of the System and Security menu.
Tip: If your antivirus software has a firewall, use it for a smooth combination with your antivirus.
