I have a customer who uses an application called Dentrix. It is a dentistry related program. One of it's features is to submit claims over the internet. When NOD32 is set to do real time scanning, the application hangs trying to submit claims. It will just sit there in "Not Responding" limbo until I disable real-time scanning at which point it continues on as normal. While the application is hung, ekrn.exe is pegging the CPU. I have tried adding exclusions for the application folder in the program files files directory and the data folder on the network share. I have tried turning off HTTPS checking. Anyone have any ideas what else I might try to get this working? Currently I have uninstalled NOD32 on their main workstation and installed microsoft security essentials so they can get work done. It works fine! It however is unmanaged so this is just a temporary solution while I try to get NOD32 working.
