I have posted this in the Kaspersky forums too, but am mentioning it here in case it is somehow related to FD. Using FirstDefense-ISR I updated my Primary Snapshot from a KIS Test Snapshot, did a PerfectDisk Offline Defrag, and after booting into the Primary Snapshot, all applications that request net access had this alert popup. At the moment, I can't figure out what is supposed to have changed. I did boot back into the KIS Snapshot just to see if the same popups occurred, but nothing happened so that kinda rules out PerfectDisk, I think. Example of AH alert relating to MSN Messenger follows.
