Hi there,
Former Kaspersky user over here. I installed NAV '09 a couple of days ago and have been enjoying the "pulse" updates and the nice UI along with the quick scans and small memory footprint.
Anyhow, it seems that there's a problem with the update feature. I ran Liveupdate on the first day and it downloaded definition and program updates along with a bunch of other stuff. All updates were successfully applied. However, everytime I manually click on LiveUpdate, it starts downloading a 35MB file. I thought it was another program update the first time but even after numerous restarts, the same thing keeps happening over and over again. Auto-update doesn't seem to download that mega update or whatever that 35MB file is.
The current version on my computer is 16.2.0.7 and my subscription status is active, if that matters. I've re-installed it once already, in case someone suggests doing so.
