What became the heuristic mode?

Hi,

I remember the Windows Norton Internet Security had a heuristic (behavioral) mode of detection.

I hoped to see this for the Mac version.

The Windows and Mac versions have an unified interface, but in place to come in the Mac version, I remember it disappeared from the Windows version.

A possibility, is since the good processor i3 to i7 and the inefficiency of a simple alone anti-virus, the heuristic mode would be set at the "Strong" level anyway - so we could not set it any other way.

Could anyone give me this confirmation, or infirmation?
