2 Files in the latest Microsoft Office 2013 patches identified as Suspicious.Cloud.7.EP

In the latest Office 2013 patches released from Microsoft yesterday, mscss7cm_en.dub and mscss7wre_en.dub are identified as the threat Suspicious.Cloud.7.EP by Norton Antivirus 21.0.1.3.  Are these truly threats or misidentified as threats?  Thanks!
