Both a virsu scan and a deep system scan identify the following Trojans
Gen:Trojan.Heur.4201FE7B7B and
Gen:Trojan.Heur.6320DF5A5A
These are from files that have been on my computer for a long time and BD did not previously identify them. In addition, they are setup files downloaded from a very reputable company.
Thank you for your help.
