 General Comments: 
       The Traceback II virus is a variant of the Traceback (3066) virus. 
       It is believed that Traceback II predates the Traceback virus, 
       however the Traceback virus was isolated and reported first.  As 
       with the Traceback virus, the Traceback II virus is memory resident 
       and infects both .COM & .EXE files. 
       The comments indicated for the Traceback virus generally apply to 
       the Traceback II virus, with the exception that the file length 
       increase is 2,930 bytes instead of 3,066 bytes. 
       Known variant(s) of Traceback II are: 
       Traceback II-B: Similar to Traceback II, this variant will infect 
                       COMMAND.COM.  When the cascading effect occurs, the 
                       screen will not be restored, instead the system 
                       will be hung requiring it to be powered off and
