We recently setup a Synology DS218+ NAS at the office, mainly to share files on our office LAN. The NAS's antivirus app flagged 3 instances of "MFCX.dll" as being "Win.Trojan.Agent-6014684-0". Each instance of MFCX.dll was found in a separate folder on the NAS. One was found inside a folder which has "Window_RunTime" in its filename. Inside that folder were a lot of other *.dll files which were created by FileMaker for Windows -- FM Pro version 8, possibly. In fact, in every folder in which the supposedly infected MFCX.dll was found, there were many other FM-generated DLL's.
Did the anti-virus app on the NAS quarantine these MFCX.dll files by mistake, or even if MFCX.dll is a legitimate FileMaker Pro generated file, could MFCX.dll have been infected by a trojan? I don't see how only those files could be infected, since those 3 files were the only quarantined files on the entire NAS and we have a huge number of Mac and Windows files on that NAS.
I look forward to hearing your thoughts.
