To protect your computer, keep its software updated, secure your home router and online accounts, be cautious with unexpected messages, and back up important files. These steps work together: no single setting or security product prevents every threat. Start with the checklist, then follow the sections that apply to your device and accounts.
- Turn on automatic updates for your operating system, browser, security software, and frequently used apps where available.
- Replace your router’s default administrator credentials, enable Wi-Fi encryption, and check for router updates.
- Use unique passwords and enable multifactor authentication (MFA) on important accounts.
- Verify unexpected requests through a channel you already trust; don’t open suspicious attachments or share personal information in response.
- Back up irreplaceable files to an external drive or a carefully chosen cloud service.
How do I keep my computer’s software secure?
Turn on automatic updates wherever they are available for the operating system, web browser, security software, and apps you use regularly. Updates can include security protections, so postponing them indefinitely can leave known weaknesses unaddressed. The FTC advises: “Turn on automatic updates to keep up with the latest protections.” FTC guidance on automatic updates
On Windows, open Settings > Windows Update to review update status and available options. Microsoft says Windows devices include Windows Security; the exact controls can vary by Windows version. Check Microsoft’s current instructions for your device rather than assuming you need to buy antivirus software to get started. Microsoft: Keep your computer secure at home

- Replace the default administrator name and password with credentials that are difficult to guess.
- Enable wireless encryption using a security option supported by your router and devices.
- Check for router software or firmware updates and install them using the manufacturer’s instructions.

What is the safest way to back up important files?
Make copies of files you could not easily replace—such as family photos, personal documents, or work you create—to a separate external drive or a properly vetted cloud service. Backups are valuable when files are lost, a device fails, or malicious software interferes with access to data.

External drive or cloud backup?
| Choice | What it offers | What to consider |
|---|---|---|
| External drive | A separate removable copy that can be kept disconnected between backup sessions. | Store it safely, reconnect it for backups, and disconnect it afterward so it is less exposed to problems affecting the computer. |
| Cloud backup | Files stored away from the computer, accessible through the service’s recovery process. | Evaluate the provider’s security and privacy practices and understand how you would restore your files. The guidance cited here does not compare specific services. |
CISA recommends using an external drive or cloud service for backups and disconnecting an external drive when it is not being used for backup. The FTC also advises backing up important computer information. CISA: How to Protect the Data that is Stored on Your Devices · FTC: Five things to do to protect yourself online
If you encrypt a device or backup, first make a backup and securely store the recovery information. Encryption can help protect data if a device is lost or stolen, but losing the recovery key or other recovery details can prevent you from accessing your own files. CISA guidance on protecting stored data
What if my computer is managed by work or school?
Follow your organization’s IT and security policies on managed devices and accounts. Don’t change settings, install software, or move work data to a personal backup service unless your organization permits it. Ask your IT team how to report suspicious messages, handle updates, and back up work files.
