You're right, Rooster. Law enforcement gets very difficult on the Web. But Wat is right, too. Education would help but there's no cure for stupidity.
What do you think of this darn Ransom ware that's hitting innocent people? No way to prevent it.
Sure there's a way to prevent it ... Don't open any attachment, unless you are 100% positive it's safe.
Our IT department had to "scrub" a virus from the hospital computers a few months ago, because somebody was reading their personal email at work and opened an attachment from an advertisement. It took a week to get it out of all the "nooks and crannies" in the network - and we're a small hospital.
Or somebody falls for the "warning" about a virus, when they are browsing online and clicks on the link to "clean" their system.
It's all about education.
