Running NOD32 (v3.0.566.0, 2734db) w/ Outllook 2007 Ultimate on Vista Ultimate... Am getting the dreaded "The add-in 'ESET Outlook Plugin'... cannot be loaded and has been disabled by Outlook. ..." out of memory/system resources messages. Sometimes if I wait for the error dialog frenzy to stop, I can close them and close Outlook, but other times I have to reboot and/or use task manager to kill Outlook -- only to have the same thing happen a little later. This has happened with Outlook'07 with both the 2.7 and 3.0 versions. I've followed the various recommendations -- repair Outlook uninstall NOD32, check registry for EMON in Exchange/Client addin (delete if there), reboot, open Outlook, check for errors (none), close Outlook, reinstall NOD32, reboot... (steps noted in the threads listed here: https://www.wilderssecurity.com/showthread.php?t=171234 ) Unfortunately it appears that even with repair/rebuild of the extend.dat of Outlook, NOD32's eplgOutlookEmon.dll* continues to be problematic. Perhaps the extend.dat is either corrupted by the NOD32 email scanning or Outlook cannot handle sending/receiving mail along with the scanning? Or, perhaps, as I'd seen somewhere else, there's a memory leak somewhere? *I'm assuming the conflict is with the EMON dll since it was with version 2.7 -- the error message truncates the name to eplgOu~1.dll. It appears the error is triggered when Outlook checks mail, though I'm not 100% certain of this since it often occurs when I'm working on something else (a different app). All mail is POP3, so no IMAP issue (that I know of). Anyone have any other suggestions to try? I'd like to use both programs, but really would like them to 'play nicely' together -- and definitely want to have email scanning of some sort going. Also no other AV products installed aside from the Windows defender, UAC is on and the NOD32 was installed 'as an admin'.
