In case you haven't noticed, I have been a teacher for 16 years, had the second private internet account in the DFW area, and currently run a full wired and wireless net work in my house.
I'm also the campus technologist.
I am appalled by the 60 Minutes piece. The internet is NOT a dangerous place. Here are the problems I've accounted over the years.
Student teaching -- I did get to spend some of my student teaching time "devirusing" the computers at the school. It was were brought in on a floppy disk by a teacher from a teacher workshop. Yeah, I tracked it down.
My husband once infected one of his computers by using internet porn. He learned his lesson.
I did once pick up something for a few minutes because I was looking for a program I had purchased, had the registration code, but not the actual software but Windows Live Care took care of it. Learned my lesson there too.
We had had our identity stolen. Someone forged checks that had our names, phone numbers and driver's license numbers on them -- my first clue -- we've never had our driver's licenses on our checks, I want someone to make me pull the DL out before they will take the check. I honestly don't think it was done on the internet, but I certainly found it quickly on the internet and stomped it out.
We book all of our vacations online, we do our banking online, and if I can, I do things via the internet and email. I've even done my grocery shopping online and do order most of our food online. I don't do a lot of physical shopping for a lot of reasons, primarily the time issue.
So yes, the internet is pretty safe if you know what you are doing. Install a good program -- I use Windows Live Care, keep it updated and using a good service provider and you will be fine.
Also, go directly to your website, don't click on an email link to get to them, especially your banking sites.
You'll be fine. I sure am.
Oh, and the worse "virus" that has happened at our network in our district was caused by someone sending an inapprioprate message to everyone in the district and everyone hitting reply all to tell that they didn't want the message. Had nothing to do with a "hacker".
