Restoring Threat Fixing File - Bloodhound.Exploit.252

Hi, Symantec's virus removal program deleted an important excel file for me today as a fix for a Bloodhound.Exploit.252 threat.  I have used Restore Threat to get the excel file back (no problem), but when I try to open the file the virus removal program kicks in again and deletes the file again. How can I stop the removal program from doing this, alternatively bypass it somehow.  I don't believe the threat is a real threat.

 

Would be very grateful for someone's help with this.

Thanks
