I received an alert about this trojan and can't find any information about it. It is associated with c:\windows\expamapi.dll.  Using Proces###plorer, this DLL is associated with a bunch of other processes:
    * explorer.exe
    * svchost.exe
    * MOM.exe
    * CTDVDDET.exe
    * CTSysVol.exe
    * DLLML.exe
    * CTHELPER.EXE
    * Dropbox.exe
I'm wondering what this trojan is and how to clean it. Any help is appreciated.
