Doug,

As I previously reported in the other thread, this is not exclusive to MSSE. I have clients that have been affected using Avast as well. And it has nothing to do with "free" software. We use MS System Center Endpoint Protection and I currently have no access to Financial Reporter.
I assure you BDO pays a large amount of money for SCEP. It has everything to do with the AV definitions.

Also, as reported by Micrososft:
"TrojanSpy: Win32/Nivdort.CW
Also detected as: Trojan.Win32.Agent.ihpl (Kaspersky), Trojan-FHOH!885352259A4D (McAfee), Troj/Nivdort-BV (Sophos), TROJ_BAYROB.SM4 (Trend Micro)"

Simply telling clients not to use MSSE is not a solution considering Avast and Microsoft are #1 and #2 in terms of AV market share worldwide.
