I want to pick your collective brains...at least those of you who are computer savvy (I suspect there are many of you out there). I've been using a PC for years now and have never really been a target of "SPAM," or much of anything else unwanted. Now, in the past week, I've been sent three separate emails, each of which carried a "worm" virus attachment. I scanned each of these with "Norton Antivirus" and so headed off potential problems. I simply deleted the infected emails without downloading. My questions are these; is this a common occurence? Do such emails generally target one person at a time (these aren't group or bulk mailings)? What action should one take? Who does this sort of thing and why? Many thanks in advance for any enlightenment.
