Turn on automatic updates for every bit of software you have installed on your computer. This is what all security experts recommend and, more importantly, what they do.
The researchers found that not only was installing updates the most commonly cited practice that experts do to keep safe online, it was also the largest difference between experts and non-experts: 35% of the former mentioned it, while only 2% of the latter.
You should do it too. It will leave you much less vulnerable to attacks and infection. This obviously 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.”
