I don't think you're smug, I think its a combination of good AV and anti-scumware programs and more importantly knowledge of your own machine.
Just as an aside, a work colleague who I was speaking to on the phone said that he had installed SP2 he was running Windows XP, he commented that things were not working right. I asked him what AV he was using and to my horror he had no AV or anti scumware programs. After a few Anglo-Saxon expletives from me, I think idiot came into the conversation somewhere, I persuaded him to uninstall SP2 and to install Avast, Adaware and Spybot. Avast found 58 assorted virus and trojans and Adaware found 53.
The point I'm making is that the nasties are still there, but people like your good self are getting more expert at trapping the little critters using the tools available.
Keep up the good work!
