WinXP pro + NAV2002 pro + most recent LiveUpdate version. LiveUpdate refuses to update my virusdefs automatically. NDETECT.EXE is automatically executed via Scheduled Tasks, but even when there is an update available, LiveUpdate won't download and install it. Forcing the scheduled task to run, does not help at all... It seems like no updates are detected... When I run LiveUpdate manually, everything works just fine... Does anybody know what the problem can be?
