I have been running my NOD32 now for a few weeks and I'm very happy with it. I have noticed one thing though. I shut down my PC every night. The time it takes from when it says, Windows Is Shutting Down, to when it actually shuts down, seems to take longer than it did when I was using NAV and then PC-cillin. It's only a few more seconds, but.......... Just wondering if anyone knows what causes this. Is NOD32 going through a system check before it lets windows shut down? My OS is XP Home if that makes any difference. No big deal, just courious.
