So after recent events on the news, I finally decided to secure my browsing. I heard many options and wanted to ask about VPN. Is it secure? Is there a good free VPN service available? How do I know if "tunneling" really works? How does it work exactly and how does it differ from Thor network. I am new to this and want to make all the right choices. Thank you.

Also what is the different between Encrypted & private web browsing and PPTP. While I get the basic concept, I'd like more details.

Are you only looking for free solutions?

At this time yes. I feel it kind of defeats the purpose of privacy if I give away myself by paying a monthly fee. But I may be wrong. In any case, I want to start with a free solution, but a solid one. I saw some stuff on download.com but don't just want to get something. Also, if the connection encrypted do VPN owners see my activity? For example if I buy a song on Amazon, do they see my credit card connection and that I actually downloaded the song? Or if I go to Hulu, Etc.

I'm not sure I'm following you. To whom do you want to be anonymous?

Because you understand that if you buy something on Amazon, Amazon will know who you are, with or without VPN.

Good point. To my ISP. Let's say I don't want them to see where I go on the internet and what I buy/download/read or which web-sites I visit. Also to search engines that send me ads based on my location.

I also want to know if VPN owner see all of the above, with encrypted connection.

Classic VPN will encrypt your communication between you (the client) and the VPN server. So your ISP doesn't see where you are surfing, only that you have a VPN connection to a specific VPN server (i.e. they can identify the VPN server).
The VPN server decrypts your data, so they see what you are doing. If you don't want them to see the details of your communications, you need to use extra encryption (TLS/SSL, e.g. HTTPS). Then they can see to what servers you are connecting (like Amazon), but not the content of connection.

You also need to be careful that your DNS requests go through the VPN tunnel, otherwise your ISP sees all your DNS requests and can deduce what websites you are accessing. Most VPN solutions tunnel DNS request, but for some you need to explicitly configure this (like for an SSH tunnel).

Tor achieves extra privacy by disassociating the incoming and outgoing Tor servers, and anonymizing your connections between these servers.

With tunneling can VPN Server see what I am doing? Generally which is better L2TP/IPSec or PPTP. I understand that PPTP is only tunneling, but according to Wikipedia, it may use Encryption that is commonly packages with it according to Wikipedia.

That is extremely interesting. Any reading/web-sites you recommend I view to learn more?

I got me Tigervpns for my android phone. Is this good for Wi-Fi protection?

Yes.

L2TP is more recent than PPTP.

I don't know Tigervpns. But it's a good idea to use VPN on your mobile device when you use open or untrusted WiFi access points.
