How to Keep Your Computer, Mobile, and Devices Safe Online

Online threats are constantly evolving — from phishing scams and malware to identity theft. Whether you’re on a desktop, laptop, tablet, or smartphone, protecting your device is no longer optional. This guide covers the best free tools and simple steps you can take to stay secure in the digital world.

1. Keep Your Software Updated

Always ensure your operating system (Windows, macOS, Android, iOS) is updated. Updates often include critical security patches that protect you from the latest vulnerabilities.

2. Use a Trusted Antivirus or Security Suite

Antivirus software is your first line of defense. Here are some free and reputable options:

• Avast Free Antivirus – Great for real-time protection.
• Bitdefender Free Edition – Lightweight and effective.
• Kaspersky Free Antivirus – Award-winning threat detection.

3. Install an Ad Blocker & Anti-Tracking Extension

Many threats are delivered through malicious ads or trackers. Browser extensions like uBlock Origin or Privacy Badger can help improve both your security and privacy online.

4. Use a VPN When on Public Wi-Fi

A Virtual Private Network (VPN) encrypts your internet traffic and keeps your data private. While paid VPNs offer the best features, ProtonVPN provides a solid free plan for basic security.

5. Avoid Clicking Suspicious Links

If something looks too good to be true or unfamiliar, don’t click it — especially from emails or pop-ups. Always verify links and email senders before engaging.

6. Set Strong & Unique Passwords

Use a password manager like Bitwarden to store strong and unique passwords for every site. Never reuse the same password across multiple services.
