Ensure that your operating system, antivirus software, and other applications have automatic updates enabled. Updates often include security patches that fix vulnerabilities and protect your computer from new viruses.

3. Be Cautious of Email Attachments

Viruses often spread through email attachments. Be wary of opening attachments from unknown senders, and never download or open suspicious files. Use an email filtering system to detect and block potentially harmful emails.

4. Avoid Clicking on Suspicious Links

Phishing attacks use deceptive links to trick users into revealing sensitive information. Avoid clicking on suspicious links in emails, social media messages, or websites. Hover over the link to check its destination before clicking.

5. Use a Firewall

A firewall acts as a barrier between your computer and the internet, monitoring incoming and outgoing network traffic. Enable the built-in firewall on your operating system or install a third-party firewall to add an extra layer of protection.

6. Regularly Back Up Your Data
