Having been one of the lucky prize winners, I have been playing about with NOD for the last 24 hours. And I am very impressed. Amon is causing no slowdown on my Win2000 system at all, and in fact everything has speeded up since I installed NOD as my Primary AV. But since I like to tinker I would like to have Amon fully optimised. In the Amon Setup, the default settings are set to scan all files on open, create and execute. And these are the recommended default settings. Can someone answer the following; 1. What are the differences between these scan options and why are all three recommended to run? 2. Other memory check programs such as BOClean check ONLY in the READ-only mode and there are no WRITES. Does NOD have a similar check method? Or with the default settings, does it check each file with every read/write operation? If the latter, it would appear to be some sort of duplication and therefore would this potentially slow down AMON?
