Trojan Horse

  During a daily scan, a Trojan Horse was found.  The name was Trojan.gen and it had nine traces.  The program put all the files in quarantine, where they supposedly they cannot harm my computer.  I then reran the scan, scanned with Malwarebytes', SUPERAntiSpyware and NIS2010 and they didn't find anything.  I then went to safe mode and reran all the scans and again nothing was found.  The only unusual thing I can remember doing was I ran the Adobe Reader update from 9.3.1 to 9.3.2.  The traces were found in C:\hp\recovery\wizard\fscommand.  I looked in that folder and it still shows the nine files. 

  Since the scans found nothing, can I really consider my computer safe?  A lot of these posts replies seem to indicate the "Parent" trojan may be somewhere else and can still activate the trojan.

  Since the files are in quarantine, should I leave them there or just go ahead and delete them?
