To quote my own Mother, "I don't want to learn all that technical stuff, I just want to use my computer".
Yea, I have to say, I have to clean her machine off of crap every year. Every time I go over there, Internet Explorer has 5 or 6 toolbars installed because she clicks on everything.
And no, she won't let me restrict and lock down the machine, I've tried that.
Then she shouldn't be allowed anywhere near any computer that's connected to the Internet.
An Internet connected computer in the wrong hands can be a very dangerous threat to the rest of us who share the Information Super-Highway with her. Her incompetence and irresponsibility can seriously hurt a lot of people very quickly.
She is behaving like a person who wants to drive a car but is not interested in obtaining a license that proves she knows how to operate said motor vehicle is a safe manner. She just wants to get on the road. To hell with leaning how to drive!
If she cannot take the time to learn how to safely operate a computer connected to the Internet or cannot demonstrate that she knows how to do so, then she should NOT be alowed anywhere near one.
At least not without close supervision.
