Yep, they're still infected...
I also had a fake error screen pop up over the weekend on a computer running ....... Plus. Looks like a JavaScript injection of some sort.
The scammy ad I received said that my computer was infected with a virus and provided a 1-800 # to call... So I did... and so have a dozen or so friends. Our goal's been to waste their time as much as possible. So we'll call while cooking, folding laundry, or at work while I'm working on reports. We've been trying to stretch out the calls to at least 30+ minutes each time and so far we've been able to do so.
