Hi Joe,
There were reports that came out in November of last year about a trojan that targeted a specific SAP client (saplogon.exe) along with several other companys' programs and tools. A Google search will provide links to detailed articles about the threat. There is no indication that it is a threat to BPC or the EPM Add-in. Every current and updated antivirus tool should already provide protection against this specific trojan.
Thanks,
Scott
