Have had it on my computer for several years, but have found the last live definition update was in 04. Is it still active? I tried to download it again, but my computer can't open or run the setup file - ?? Can someone shed a little light on this? I also re-downloaded Sygate Personal Firewall, and then restarted. Upon restart, Zone Alarm asked if I wanted to allow connection to something called NDIS - I did not allow, but then Sygate couldn't find the update link. Is this NDIS what Sygate was trying to connect to? Thanks much!
