If you use a VPN, your IP address is changed and your online activity is encrypted, so you cannot be tracked. Some internet service providers (ISPs) or websites may know that you’re using a VPN, but they can’t see your actual online activity. So, you should use a VPN to minimize your chances of being tracked online.

If your privacy is compromised, an anti-virus program or firewall does not secure your personal freedom on the Internet, nor does it protect you. Nor does it guarantee your Internet privacy. A firewall tracks network traffic and can protect you from unwanted access if appropriate, while anti-virus software exclusively focuses on harmful software.
