Keeping your computer and phone safe in Spain: antivirus, updates and backups

When you live in Spain, your phone and laptop hold more than photos. They hold your digital certificate, your Cl@ve access, your banking apps and scans of your passport, NIE and rental contract. Losing them to malware, theft or a broken hard drive can lock you out of Spanish bureaucracy for weeks. This guide covers the three basics of keeping your devices safe: security software, updates and backups, plus where to get free help in Spain if something goes wrong.

Why your devices matter more in Spain

Spanish public services are increasingly digital. Many residents use a digital certificate installed on their computer, or Cl@ve on their phone, to file taxes, book appointments and download official documents. Our guide to the digital certificate and Cl@ve explains how they work.

• Anyone who gets into your computer could misuse an installed digital certificate.
• Your phone is often the second factor for your bank, Bizum and government logins.
• Scanned documents stored on devices are valuable to identity thieves.

Keep everything updated

Updates are the single easiest way to stay safe, because many attacks use security holes that have already been fixed.

• Turn on automatic updates for your operating system, browser and apps on both phone and computer.
• Restart when asked: many updates only take effect after a restart.
• Check older devices: once a device or system stops getting security updates, it becomes riskier to use for banking and official procedures. Microsoft ended standard support for Windows 10 in October 2025, and its consumer extended security updates programme ran for one more year, until October 2026. If you still use Windows 10, check in your settings whether your PC still gets security updates, and consider upgrading or replacing it.
• Apps from official stores only: download apps from Google Play or the App Store, and banking or government apps only via links on the official websites.

Antivirus and security software

Modern operating systems include basic protection, and for many people that is a reasonable starting point if it is switched on and up to date. Extra security software can add features such as protection against malicious websites, phishing warnings, anti-theft tools and protection for several devices in one place.

• Use one security program at a time. Running two antivirus programs together can cause conflicts.
• Download security software only from the maker’s official website or app store. Fake “antivirus” pop-ups are a common scam.
• Do not forget your phone, especially if you use it for banking.

If you want a dedicated product, Panda Security (ad) is a maker of antivirus and device security software for computers and phones. Compare what each plan includes and how many devices it covers before you choose.

Back up the things you cannot replace

A backup protects you against theft, broken devices and ransomware, which locks your files and demands payment. Spain’s national cybersecurity institute, INCIBE, recommends the 3-2-1 rule:

• 3 copies of your important information
• 2 different devices or types of storage, for example your laptop and an external drive
• 1 copy in a different place, such as a cloud service or a drive kept at a relative’s home

INCIBE also warns against relying only on cloud services, because they are outside your control. Practical tips:

• Make a folder with scans of your passport, NIE or TIE, padrón certificate, contracts and tax returns, and include it in every backup.
• Keep a backup copy of your digital certificate file in a safe place, protected with a strong password.
• Unplug the external drive after each backup, so ransomware cannot reach it.
• Back up more often the files that change often, and check now and then that you can actually open the copies.

Passwords, two-step login and everyday habits

• Lock your devices with a PIN, fingerprint or face ID, and turn on “find my device” so you can locate or wipe a lost phone.
• Use different passwords for email, banking and government services. A password manager makes this easier.
• Turn on two-step verification for email and social media accounts, especially the email linked to your bank and Cl@ve.
• Be suspicious of messages: fake SMS and emails pretending to be from the DGT, Correos or your bank are common. Read our guide to online scams in Spain.
• Take care on public networks: see our article on whether public Wi-Fi in Spain is safe.

FAQ: device security in Spain

Do I need antivirus on my phone?

Keeping your phone updated and installing apps only from official stores covers the basics. Extra security apps can add features such as anti-theft tools and protection against malicious links, which some people find useful if they bank on their phone.

Is it safe to keep my digital certificate on my computer?

It is common, but protect it. Install it with a password, keep your computer updated and locked, and keep a secure backup copy in case the computer fails or is stolen.

How often should I back up?

It depends on how often your files change. INCIBE suggests adapting the frequency to how important and how changeable the information is. Many people back up weekly or monthly, and after any important new document.

Can I get help in English from 017?

The official information does not state which languages are offered. If you are not confident in Spanish, try the WhatsApp or Telegram channels, where you can write your question and translate the reply.
