AFAIK, PPTP isn't really that save, you do want OpenVPN.
And depending what you want to so, keep in mind,
Hidemyass.com (and other "free" VPN services) keep

Another issue is speed."Free" VPNs are unlikely to
be stable and fast.
torrentfreak has surveyed VPN providers and
asked the community. They have a list of
affordable VPNs, which do not keep log files.https://torrentfreak.com/which-vpn-providers-really-take-anonymity-seriously-111007/
