Security Risk definitions

Hello,

Suspicious risks (Security risks) are manage in the Antivirus policy. Settings for these applications are different than Virus and Spyware.

But are the definitions updates separated ? Of is it the same for "Virus and spyware" and "Security risks" : 'Virus  and Spyware definitions' ?

Sonar definitions are in another content type it seems, but which one (I can see a lot of Sonar content types but not an explicit one for definitions).

Thanks in advance for your help,

Regards
