I think the best approach is to manage the risks as you cannot avoid them. I use Windows and Norton on-line updates so I do keep my computer up-to-date. I have all the generally recommended security measures for a home computer. I also regularly back up all of my data. So far this has been fine with no virus attacks getting through the defences. I have had two serious disk faults but lost no data due to the back ups.

In contrast, I have two friends who are so concerned about security that they will not even connect to the internet but both have recently suffered from fraud (debit card fraud in one case and credit card fraud in the other).
