SEPM Locate Client culprit

My Company is running SEPM 12.1.6608.xxxx on Win Server 2008 R2 and  we have Windows 7 Client systems. A file was placed on one of our shares and has propagated to other folders. It currently has not done any damage. We think symantec has recognized the file and stopped it from shutting down our server. 

I would like to find the cllient system/s that dropped these files. Can SEPM provide me that information?

I can't seem to locate anything related to the files in SEPM.

See image for files

I believe the txt and the html may have the virus in it so I will not attach them to this post

I am very new to managing SEPM and have not had any formal training. This was recently handed to me. 

Thanks,
