Internet Security?

Nowadays, there are a lot of people using internet to do a lot of things such as online shopping, online banking, online networking and etc.
Well, are you trust in the internet? internet is the virtual network which you cannot touch and communicating face to face. And seriously, internet is not secure at all. and i believe that a lot of people cheating about themselves in the internet for whatever reasons.
So, how you will trust in the internet stuffs? personally, i do not really trust the internet especially social networking websites and the online shoppings. i always doubt that the information of the social network is true or just being made up. you can just be anyone that you want to be in the internet but in fact you are not the person.
The news always reported that there are some youngster running out from home just because of the friends in the internet. They never met each other before and they are willing to running out from home because of him/her. So, just  be rational when you are using internet.
