I have an ongoing issue since version 5 & am now using version 6 that has the same issue. I run an indepth scan and whenever Nod32 encounters a folder with large files it just hangs on the scan. I've left it run for over 12 hours and it stays on that same folder. Pressing Pause does nothing, stopping the scan does nothing in terms of actually pausing or stopping it but it will show the message waiting to pause and waiting to stop scan when stop is pressed so the program itself is not hanging just the scan. I had it happen on a folder that stored a cache of musical waveforms but because I could delete that folder without issues the virus scanner would get beyond that folder but now it hangs on my folder windows\winsxs\Manifests.
