What anti-virus or security measures should I take to protect my PC from viruses and malware?

1. Install a trusted antivirus program and keep it updated: Ensure that you have the latest version of a well-known, reliable antivirus program installed on your computer and that it is regularly updated with the latest virus definitions.

2. Update your operating system: Keeping your OS up-to-date with the latest security updates is key to staying protected from malware.

3. Use caution when opening emails and attachments: Be careful when opening emails, especially if they contain attachments, as they can contain malicious software. Never open an email attachment unless you are sure it comes from a trusted source.

4. Use strong passwords: Create strong, unique passwords for all of your accounts, and use two-factor authentication for additional security.

5. Install a firewall: Firewalls can help protect your computer from outside threats by blocking malicious traffic from entering your system.

6. Avoid using public Wi-Fi: Public Wi-Fi networks can be easily hacked, so it’s best to avoid them whenever possible. If you must use one, make sure you are connected to a secure network.

7. Back up your files: Regularly back up your important data to an external drive or cloud-based storage. This will ensure you have access to your data in the event of a malicious attack.
