Just installed Avast on my computer in place of Norton which had expired.
Since then, each time I try to open Outlook, Outlook crashes down.
I started my computer several times again, but nothing changes.
I uninstalled Zone Alarm Pro, cause I thought this could be the cause, and replaced it with Kerio…Nothing…
Please, browse the Symantec website and download the specific uninstall tool for NAV. It will clean trash left behing by NAV (files, registry keys). You need this to proper working with avast.
Can you try to repair your installation? Go to Control Panel > Add/Remove programs > avast! antivirus > Remove then choose Repair function in the popup window (Repair). If this does not help, can you uninstall / boot / install / boot again?
You can delete folders/files under either ‘Norton’ or ‘Symantec’ folder, the others under Liveupdate folders and ApplicationData…
Without proper uninstalling NAV, I can’t see other light for this.
Which is your Windows?
Did you check if avast! plugin is enabled into Outlook? (suppose you’re talking about the full one, not Outlook Explorer).
