Hi, i am having a laptop with Windows Vista that i mostly use at the public places connected with WiFi. It is obvious that i am not safe to use wifi on public places in terms of my personal data, passwords, etc. So i came to know that there is an application named Tor that can help me in securing my system. At present i don't know anything about Tor. Could you guys please give me some important info about and how to create a secure VPN with Tor ? Any help will be appreciated.
