I have just installed NOD32 v4 Business Edition on to my network and it is now taking forever to open any files on my server from a client machine. I have discovered this is the realtime scanner on the server and I have to uncheck the Scan On: File Open, File Creation and File Execution checkboxes in Real-time system protection. This effectively defeats the whole purpose of the software. Has anyone else had this issue? Any suggestions? I have tried excluding the entire Windows folder on the server and it makes no difference.
