I generally help family who are local, usually when I am going over anywhere or they invite me for a meal after work. Luckily I rarely get calls from people wanting help on getting a certain piece of software to work.
I did however have two problems reported to me in the past weel week: 1) a friend of my mother's found £230 of international satellite calls on their bill after a dialler somehow got installed, and 2) my uncle has a pr0n dialler on his machine which put £17 of calls on his bill last month.
Both will be receiving attention - the first one has only been reported from Germany so far, so it's worth a look just to report to the newsgroups as a "heads up" on where it came from.
