Couldn't agree more. I check windows update 3-7 times a week, and AV/Spyware updates at least every day. Got a few antispyware programs, too. Still the trojan did it's thing, possibly because it's a fairly new variant, I don't really know.
So even with everything up to date, which is important security, new spyware/virus are being developed. A bit like bugs/flu evolving in advance of medical practice.
(In fact, IMO, the analogy is a bit scarily accurate)
BTW, I now have 2 more antispy programs than I did a week ago.
