I kinda got that impression that there has been many smaller hacks that have been increasing lately to the point that the US Homeland Security Agency finally issued their warning as it is now a major hack. I guess that they do some decent work; however, they tend to be very good at alarming the public as well, needlessly sometimes I think.
I checked my machine & it doesn't seem to be on it. My wife's laptop with Vista may be another story. I hate mucking around with it as Vista often baffles me, although that isn't hard to do these days, ha!
