hi,pal!The following is my view,i wish it could help you and solve the currently issue.

As the world gets more globalized,the most we need internet to be in touch with friends all over the earth and to absorb information.I′m not the kind “internet animal”,but I daily use the internet to know about breaking news,searches,and to know if my friends are doing well.It gave the possibility of real video chatting,what I often do with my dudes,and to maximize our skills,what probably most of us are doing right now.Even though all advantages,this is not all seems to be.On the other hand internet can be used to spread pornography,crimes,apology to the drugs as well.So we can not be safe in our own house if we don′t fend off some security aspects.Not having a good security firewall,control of what children access,and a good “how to use” policy internet can be a downer.
