Protecting your computer from malware involves a combination of good practices and the right tools. Here are a few expert-recommended actions you can follow:

1. Install Antivirus Software: Use an anti-malware app and keep it up to date to defend your PC against viruses and other malware.

2. Enable Firewall Protection: Firewalls can help block unauthorized access to your computer.

3. Regular Updates: Keep your operating system, web browser, and other software updated. Regular updates often include patches for security vulnerabilities.

4. Exercise Caution with Emails and Downloads: Be careful with emails from unknown senders and downloads from unfamiliar websites. Many viruses are attached to email messages and will spread as soon as you open the attachment⁴.

5. Use a Pop-Up Blocker: Pop-up windows can contain malicious or unsafe code. Using a pop-up blocker can prevent some or all of these windows from appearing.

6. Secure Your Network: Make sure your Wi-Fi network is secure, use a strong, unique password, and consider using a VPN when accessing the internet on public Wi-Fi.

7. Implement Multi-factor Authentication (MFA): MFA adds an extra layer of security by requiring more than one method of authentication.

8. Regularly Back Up Your Data: Regular backups can help protect your data if your computer becomes infected with malware.

9. Secure Mobile Devices: If you're using mobile devices, make sure they're also protected with appropriate security measures.

10. Regularly Monitor Accounts: Regularly check your online accounts for any suspicious activity.

Remember, no single method can guarantee complete protection against malware, but combining these methods can significantly reduce your risk.
