misidentified file?

i spent the whole day the other day downloading a game only for Sonar to remove it when it was finished.

 

i contacted the developers about it and they swear up and down that it's a false positive.

 

here's the log:

Category: SONAR Activity
Date & Time,Risk,Activity,Status,Recommended Action,Path - Filename
6/16/2011 6:11 PM,High,prodinfo_fbiparanormalcase_1.0.1.1509.exe (prodinfo_fbiparanormalcase_1.0.1.1509.exe) detected by SONAR,Removed,Resolved - No Action Required,c:\programdata\wildtangent\wtdownloader\fbiparanormalcase\download\prodinfo_fbiparanormalcase_1.0.1.1509.exe 

 

any suggestions?
