Using a VPN will not keep your browsing habits anonymous, nor will it add additional security to non-secure (HTTP) traffic.
If you are looking for anonymity, you should use the Tor Browser instead of a VPN.
If you're looking for added security, you should always ensure you're connecting to websites using encrypted DNS and HTTPS. A VPN is not a replacement for good security practices.
If you're looking for additional privacy from your ISP, on a public Wi-Fi network, or while torrenting files, a VPN may be the solution for you as long as you understand the risks involved.
