Very true words Adrian,but try stopping what really amounts to an epidemic,its like a monster that is out of control.Millions,probably billions just posting total irrelevant drivel all day long.
My niece is 25 and after work that is all her life consists of.She has a £500 Dell lap top which in the 3 years she has had it has only been used for Facebook.
The lap top had a some malware on it about a year ago which I managed to sort out for her(but she didn't know how it got there as she hadn't done anything)
It has the same thing again,but I have refused to do anything so now she just uses her i phone to do the same.
