Its kind of scary?

As a computer technician, and using RAT to 'spy' on the computers in my home entwork I can see several members of the family visiting adware ridden sites, downloading 'free' p2p networks and stuff, ive told them umpteen times to avoid doing it, as well as many of my customers. How do I teach them to look after themselves on the net? Every day I see vulnerable people buying computers and end up ditching them because they get burned by the unpleasants found on the internet, what do I do to show these people how to defend themselves on the cyberwar front?

thanks for you nice thoughts of learning people, but its hard work, extremly hard!!, you need to learn them every thing about computers in order to let them chose wheather to get something from the net or not, but you can do it in another way, advice all of them to install internet security softwares, like Norton, this is the easiest way.

If you have advised them, told them and instructed them, your options are a bit limited.

you can ignore them, protect them or punish them.

as a tech with a home network, a decent linux firewall/gateway should be well within your abilities, you can use that to protect (by blocking repeat visits to dodgy sites), or punish (by temporarily refusing connections from those computers)
