    Hi there

    Got NOD32 Antivirus on my computer and have been increasingly frustrated with the lack of speed for my connection through my LAN to my NAS.

    When I disable it, the computer accesses the files very quickly without disruption, but when I enable it, everything grinds to a halt. So I either have virus protection and a 'stalling' and sometimes crashing access to my network storage, or I have virus protection.

    I have just disabled the HTTP check as recommended, but it's still not great!

    Does disabling any of these options on the NAS make a difference?

    Thank you, have tried that and things seem to have got substantially better. Greatly appreciated.

    BTW - what have I 'switched off'??

    It depends on which of the options you disabled. Most likely it was advanced heuristics (AH) which emulates the program code to determine if a file is suspicious. Since code emulation is a time/resource intensive operation, it is enabled only for new files by default. If the clients have EAV/ESS installed, it'll be enough if you enable AH on file execution and leave it disabled for new files that are probably frequently created on the server and thus slowing down the performance.
