So, there is about 4 major things wrong with this commercial:

1. XP on a MacBook, with a BSOD
2. Actually, most of the computers depicted are Macs running Windows.
3. At about :18 in, they have a Mac running windows, running IE, getting the Firefox version of the “Unable to Connect” page.
4. Finally, through the entire thing, they flash “PC Computers only,” on the bottom.

I think that the guy who put the commercial together was putting subtle clues to let people know it was a scam.  I think.

Anyway, seems they charge for free software you can easily download and run yourself. So if you were thinking about running their “Free Scan,” remember these things almost always cost you money and will probably trade your malware, viri, and spyware for theirs.
