"A damn good reason, that if you must use PC, you learn how to protect yourself"
Yes, I agree, but consider this: I've been using computers for 30 years now. I run AVG anti-virus, Zone Alarm Firewall, Thunderbird, Firefox with NoScript and AdBlock Plus, Spybot search and destroy and I don't run software I don't know the source of, yet still, last week, I found that my website had been compromised because a trojan had sneaked through an unpatched flaw and stolen my log-in and was merrily trying to redirect people to malware sites (fortunately my hosts' software controls picked it up)
The upshot of this is that, just like when I'm riding my motorbike (which, of course, I had to pass a test for), I know that despite *ALL* the precautions I take, there's always the chance that something will happen out of the blue.
So it's all very well to say "learn a little security", but don't let your smugness blind you to the fact that you, too, are vulnerable.
