I don't have any grandparents that are still alive, am much too old for that. However, my mother is in her late seventies and not very technically minded. She takes an interest though, mainly because she is proud of her son for writing books about it. Shame she didn'r read any of them though, then she may not have had to ask 'do I need to turn the computer on to receive email?'

My father-in-law, bless, had a problem whcih I thought might be down to malware. However, he insisted that he had a security suite installed and scanned his computer every week.

I went round to take a look, and the first thing I wanted to do was a full security scan. At which point I discovered that the last set of definition/signature updates was a couple of years old. Apparently he didn't bother to re-subscribe after year one, thinking that he had the application and that was good enough.

Not funny, at all, but oh so common a mistake it seems...
