Summarize this article in one sentence.
Hypertext transfer protocol secure (HTTPS) is an encrypted website connection that your browser uses when you’re accessing and viewing a web page. You can tell that the website you’re viewing is using an HTTPS connection if you see “https:” at the beginning of the website’s address in your web browser’s address bar. Many websites use an HTTPS connection that will keep your PC safer from viruses and malware. To make sure your Gmail page is always using a secure HTTPS connection, click on the gear icon in the top-right corner. Scroll to the tab labeled “General.” In the general menu, choose the option to always use an HTTPS connection.  Your Gmail settings will be saved so anytime you use it, you’ll be using an HTTPS connection. Your Gmail likely contains a lot of your important and personal information, so keep it secure with an HTTPS connection. To change your Facebook settings to use an HTTPS connection, click on the down arrow in the top right corner of your screen and select the “Account Settings” option. In the menu for your account settings, click on the option labeled “Security” to bring up the menu. In the “Secure Browsing” section, check the box labeled “Browse Facebook on a secure connection (https) when possible” to change the settings. Viruses and malware can breach your PC by using your Facebook account. If you use Google Chrome, Opera, or Firefox as your web browser, you can add an extension that will automatically request an encrypted connection whenever you visit a web page. If the page supports an HTTPS connection, then your browser will automatically use an encrypted connection. Download the extension to add it to your browser. Visit https://www.eff.org/https-everywhere to download the extension. If you sign into a public Wi-Fi connection or a connection that isn’t yours, your PC can be breached by hackers, viruses, and malware. A Virtual Private Network (VPN) encrypts your information and keeps your PC secure so you can browse safely.  You can subscribe to a popular VPN like Tunnel Bear, Cyber Ghost, or ProtonVPN. Many VPNs have a monthly fee in order for you to use their encryption services. Search online for free VPNs that you can use as well.

Summary:
Use an HTTPS connection on websites to secure your PC. Select “Always use https” in Gmail. Set your Facebook to use an HTTPS connection. Install the HTTPS Everywhere extension for your browser. Protect your Wi-Fi connection with a VPN service.
