Time to change to a mac?

I saw this ad today. It says

”Within 2 minutes my PC was tested and 253 faults in Windows was found”

Test your PC to find faults that slows down your system.

I find it quite amusing to try to understand how the pc-people think. It seems like they think it is something positive to test a PC and find 253 faults? Why not buy a computer from Apple and go for as few faults as possible from start?
