Trying to remove old quarantined virus's

I was a former user of Norton System Works.  I believe that I installed the program about 5 or 6 years ago (Long enough that I no longer have the disc).  My Internet provider was supplying Norton protection for free as part of the high speed package so I jumped onboard with them several years ago and the transfer was seamless going from one Norton product to another.  Just recently the Internet provider switched protection companies.  I was required to remove Norton, which I did in order to download the new program.  Now when I do a scan for virus’s I’m picking up 1000’s of quarantined virus’s held in a Norton quarantine folder.  I tried to download a removal program but the folder stays put.  Does anyone have any suggestion as to what I can do to remove this folder permanently?
