Backdoor.Agent.DCGen Firefox.exe?


Recommended Posts

Looking for some insight on this.  A PC I scanned came back this virus and is pointing to the user/cookies folder for Firefox.exe.  I have scanned other PCs in this organization they everyone is coming up with the same results.  These files do not exist on the PC.  They were tagged in the heuristics scan.   Is this something that is a false positive?

Thank you.

No out of the ordinary GPOs.  Just default domain with password policies.

Symantec.Cloud has no blocks or exclusions specified.  


Edit:  This folder it found is a Windows Junction Point folder that actually redirects to the C:\users\user\appdata\roaming\microsoft\windows\cookies   Yes, Access is denied on this folder by nature in windows.  You can get around it by taking ownership of it but it is just a shortcut to the mentioned path above.  


Even crazier is I have scanned PCs from different organizations under our management and this doesn't get flagged.   I have had this flagged on Windows 7 and Server 2012 on the affected organization

This is something that is unique to that environment for some reason. This def has been in quite a long time in our database. Something is denying access for our scan on that folder which causes the fp. Maybe try disabling any other security software one by one to see if the detection stops. Is this the free version of MBAM or paid?
