Turn on automatic updates for every bit of software you have installed on your computer. This is what all the nerdiest security nerds recommend. You should do it too. It will leave you much less vulnerable to attacks and infection. This goes for mobile devices too. Update apps and operating systems as soon as the option becomes available.
Most software manufacturers have teams of people dedicated to identifying the latest vulnerabilities in their products. If you’re using older versions, you’re vulnerable.
“Software updates are like oil changes,” says Mark Surman, executive director of the Mozilla Foundation. “They can be a hassle in the moment but a lifesaver in hindsight.”
