SCCM 2012 Client cache detection Trojan.Gen detection

Hi All,

One of our packaged software installations being deliverd to our Windows 8 clients via SCCM2012 is being detected as a Trojan.Gen. I was going to put in a file exception for the msi. But the SEP file exceptions require a full path. The nature of the SCCM client is it changes to path name to the installation files, e.g.

Same installer msi but differnt paths

Computer 1 C:\Windows\ccmcache\4f\<installfile>.msi

Computer  2 C:\Windows\ccmcache\5p\<installfile>.msi

 Is there any way around this? I would prefer avoiding adding a folder exception at say the C:\Windows\ccmcache level as this is the only msi affected.

Thanks
