You cannot put it in a trusted list Mcafee alone does this and only for PUPs or Potenially unwanted programs where it gives you the option. This detection I assume is not a pup so till Mcafee adds exceprions to their real time scanner (this is coming hopefully in2014 the only fix is to submit the file. What size is it?
I might be able to get a lab tech to help you but I need teh size to think about how to get it to him.
Community Interface usn't for product help, I have moved this to VirusScan for filing.
Can you please check if fifav14.exe is a legitimate file? I guess this is a crack and normally such files are malicious. That might be the reason why the file is quarantined by McAfee.
