Spotflux is a private, safe, and free Internet VPN product. It gives you an encrypted and secure connection. There is malware and virus protection and unrestricted access.

I am using Hotspot Shield Free VPN. However free version is ad supported, but its good from all other available free vpn’s. You can surf anonymously and access all blocked websites using HSS.
