Disable NAV with the tray icon and then reboot
Then do a ctrl alt del and what do you see?
NAV componets running, that's what.
"I did some checking, and NAV has a smaller system resource impact then Trend, so item #1 was incorrect as well."
Point me to your "proof", I've run both and with NAV system resources are 3% lower at boot.
"it still keeps working fine, it just doesn't get the brand new virus defs"
Then what good is it when new viruses are released?
Do you by chance work for Symantec?
