I've seen plenty of the same fake AV malware that installs itself via drive-by downloads on computers with up to date firefox installs. Security patches aren't instant. Updating your browser helps sure, but it's not a real solution. There is a tendency for people like us to assume every time we see someone with a malware infection that it must be because the user is a moron who: still uses Kazaa, doesn't know about the good porn sites, is browsing on IE6 and installs anything that a popup asks him too. That just isn't true. It's not just idiots, the average non-moron windows user is massively vulnerable to malware. In my experience (I'll limit it to friends and family b/c of the obvious selection bias of including Geek Squad customers), nearly every (non developer) windows user I know has had at least one malware infection over the last few years that required either my help, or a system restore.
