EDIT
No longer relevant since I've removed avast altogether. Spontaneous, uncontrollable reboots create way to many problems.
Thanks anyway.
I'm just beginning my deployment of Avast using Small Office Administrator and while I seem to have no issues with deploying to Domain members, attempting to install on non Domain members fails each time. I suspect it's an authentication problem, but I can't seem to find a way to have it use a local account instead of a Domain account for authentication.
Any ideas or tips ??
