Packed.generic.200 virus can not be removed!

I have been having one heck of time with this packed.generic.200 virus!  After studying on how to remove it, I downloaded avg, malware bytes, and super anti-spyware.  These three found and destroyed the virus.  And after, Norton did register it as being "removed."  It even showed in my security history as being removed.  Now the problem I have is that every time I start my computer I receive a pop-up window from Norton stating that I still have the virus.  I have run many, many virus scans after, and Norton states my computer has no virus probem.  But I keep getting this pop-up window that states the packed.generic.200 cannot be removed!  I click on the scan again, then the help, and then receive a pop-up window from Norton that says all problems have been resolved.  But the next time I start my computer, I get the pop-up stating packed.generic.200 cannot be removed.  I'm really frustrated!  I again, just today, ran all four virus scans... avg, malware bytes, super anti-spyware, and Norton... No virus was detected!  So I removed avg, malware bytes, and super anti-spyware...thinking that these programs might be interferring with Norton, and restarted my computer.  Guess what?  That pop-up window from Norton came up again and stated that the packed.generic.200 failed to be removed!  I've been told by a computer specialist that this is just a "false positive," and that the window will stop popping up in a few days.  However, it has been two months!  Please help me?  What do I need to do?
