I'm looking for some comparisons between Mcafee VirusScan and other antivirus products (and other products), all are independent (is good), but I need some chart created by McAfee itself.
McAfee doesn't usually put out comparison charts between it and other makers' products, only between its own products and those charts are all on the Consumer website such as this one: Antivirus Software and Internet Security For Your PC or Mac | McAfee.
Enterprise products, where you are now posting, are just too numerous and tend to be decided on by Corporate boards so don't have similar comparisons.
However, that doesn't rule out such charts being available from 3rd party sources on the web. Try a Google search for something like "Antivirus reviews" or similar.
