Norton AV detects and deletes Bloodhound.RLTrap every 5 minutes

Norton AntiVirus 12.1 on Mac running 10.7.3  Norton AV keeps detecting Bloodhound.RLTrap

It says it was deleted from /Library/Application Support/Symantec/AntiVirus/QTFiles

 

There is no folder by that name.   The notice is coming up every 5 minutes (exactly).  Looking it up on Symantic's website, it looks like Bloodhound.RLTrap infects PCs only.  How can I get rid of it or stop Norton from giving me a notice about it since it says the file has been deleted?
