In the process of updating Norton Anti-Virus a couple of folks over here 
have been notified that something called Trojan.Dropper was detected and 
cleaned by deletion.  I don't know that these are related but it did happen 
twice.  One of these people said that a later scan found it again.  I 
looked on line and Symantec recommends starting in Safe Mode and doing a 
scan (also with System Restore turned off).  Is this the best advice or is 
there something else to do?
