Suspicious MH690.A

After a full system scan today, Norton Antivirus quarantined 2 files detected by the virus scanner as Suspicious MH690.A .  This was done after an live update and after a reboot of the computer.  These were old games that haven't been used for years.  It chose those 2 games from many games that we have.  On one game it said it was new and it was released a week ago.  Not sure how that could be considering we haven't used the game.  The other game it said it was mature and released 5 years 3 months ago.  They were rated high risk.  We're not sure what to do.  Does anybody know how to send these files to Norton?  We are up to date on our Norton Antivirus Program.

Thank you for your help.
