Total Defense makes internet security easy for you and tough on destructive malware. We don’t just protect devices, we protect people.

Software updates can feel like interruptions, especially when you are working, streaming or trying to finish a task. But that “update later” button can leave a known security weakness open longer than necessary. Developers regularly publish patches that close vulnerabilities, strengthen privacy and fix bugs. Turning on automatic updates removes the need to remember every release and helps your devices apply important protections sooner.

The risk is not theoretical. Verizon’s 2025 Data Breach Investigations Report found that exploitation of vulnerabilities as an initial attack vector increased 34% and accounted for 20% of breaches. While that research focuses on organizations, the lesson applies at home: attackers actively look for software weaknesses, and delaying a patch gives them more time to exploit one.

Why are automatic software updates important?

An update replaces or changes software code on your phone, computer, tablet, browser, app, router or smart device. Some releases add features, but security updates repair flaws that criminals could use to install malware, steal information or gain control of an account.

CISA explains that software makers issue updates to patch security weak spots and recommends turning on automatic updates so protection arrives without relying on a manual reminder. Automation is especially useful for the software you use every day, including operating systems, web browsers, apps and security tools.

What should you set to update automatically?

Start with devices and software that connect to the internet or handle personal information. Review these categories:

• Operating systems: Enable updates for Windows, macOS, ChromeOS, iOS, iPadOS and Android.
• Web browsers: Keep Chrome, Edge, Firefox, Safari and browser extensions current.
• Mobile and desktop apps: Update email, banking, messaging, shopping and productivity apps through the official app store.
• Security software: Allow antivirus and other protection tools to receive current threat definitions and product updates.
• Home-network equipment: Check whether your router, mesh system and connected devices support automatic firmware updates.
• Smart devices: Review update settings for cameras, speakers, TVs, thermostats and other connected products.

Remove software you no longer use. An abandoned app can become an overlooked entry point, and software that has reached end of support may no longer receive patches at all.

How do you turn on automatic updates safely?

1. Open the official settings menu. Search for Software update, System update, App updates or Firmware update.
2. Enable automatic download and installation. If offered, allow security updates to install automatically and choose a convenient restart window.
3. Update apps through the official store. Turn on automatic app updates in the store tied to your device.
4. Keep the device ready. Connect it to power and trusted Wi-Fi, and leave enough free storage for updates.
5. Restart when prompted. Some protections do not take effect until the device restarts.
6. Check monthly. Confirm that updates succeeded and investigate repeated failures.

Can automatic updates ever cause problems?

Occasionally, an update may change a setting, require a restart or conflict with older hardware. That inconvenience is a reason to keep backups—not a reason to skip security patches indefinitely. Back up important files, keep recovery information current and install critical updates promptly. If you depend on specialized software for work, check the developer’s compatibility guidance while still prioritizing urgent security fixes.

How can you avoid fake update warnings?

Scammers use pop-ups, ads and messages that imitate update alerts. Do not install software from an unexpected email, text or browser pop-up. Instead, close the message and check for updates from the device’s settings, official app store or vendor website. CISA advises downloading updates only from trusted vendor sources and warns that fake update links or attachments may contain malware.

How does this help someone become safer online?

Automatic updates shorten the time a known vulnerability stays open on your device. That makes it harder for criminals to exploit old flaws, install malware or steal data through outdated software. Updates also keep browsers and security tools ready to recognize newer threats. The FTC recommends automatic updates for security software, browsers, operating systems and mobile apps because updates often include critical patches and protections.

Automatic updates are not a complete security plan. Pair them with unique passwords, multifactor authentication, secure backups and careful clicking. Still, they provide one of the easiest wins in personal cybersecurity: protection that works in the background.

Take five minutes today to check your phone, computer, browser, apps and router. Turn on automatic updates wherever a trusted vendor offers them, restart devices that are waiting for patches and replace unsupported software. A small setting change now can close the door on an attack later.

Traveling is fun. Losing access to your email, bank account, or phone while traveling? Not so much. Whether you’re heading out for a weekend trip or flying internationally, your devices carry a lot of sensitive information: photos, passwords, banking apps, work files, travel confirmations, and personal messages. A few simple cybersecurity habits can help protect […] Read More»
