Exchange 2003 hanging

Hello EE. I am trying to resolve a problem I am having with my Exchange 2003 Enterprise Server running on Windows 2003 R2 which has been running fine for years. Everytime I run my AV program the Store.exe memory consumption hits 99%. I uninstalled and reinstalled the latest version and it still hangs. It would appear to be a problem with the AV but I want to know if something else in the background is to blame. When I look at Task manager with the AV uninstalled I see the store.exe service is using over a gigabyte of memory. Yesterday it was at 850MB. I have 4GB of memory in the box. I ran EXBP and it flagged  the Recipient update services had failed or stalled. I am using ESET Mail Security for Exchange. Any suggestions would be greatly appreciated.
