Interesting, someone complaining that a scan is too quick, that's a new one!

However, I wonder if by any chance they have finally found a way for the scan engines to use more than one processor core? If so, your processor utilization during the scan should exceed the normal 25% max, since I believe this would be typical on your system as it appears it's basically a quad core?

If the reinstall doesn't change anything, take a look at this possibility and let us know.
