In Windows Security Center, it shows that Defender is turned off. When I
click to turn on, it searches for new defintions...but none are ever
found...and Defender will not turn on. However, in the Application Event
Log, there are numerous events with Defender as the source showing scans
being done each night along with other detection activity. I'm running Vista
Home Premium w/ NAV2007...both were pre-loaded on a new PC from Dell.
Any insight as to why Security Center shows Defender as off is appreciated
along with how to resolve.
