MP3 player cannot be read by PC

I have Norton Internet Security.  (Not sure which version, because I cannot find where in the software that is listed.)  The last time I ran the program, it quarantined file a0085139.exe (Trojan.ADH)  Now the computer will not read my MP3 player's library.  I read another thread posted by Porsche on 4-23-2009.  It stated to turn off the Norton 360, reload the MP3 driver, then turn the Norton 360 back on.  I tried to turn off Norton 360 thru Administrative Tools->Services.  But a pop up appears stating that I do not have access.  Is it because I may not be in the same version as Norton 360?  What should I do?
