I Use C.o.m.o.d.o Firewall On Windows Xp Media Centre 2005 Pc. I Have Tried To Search For This Norton Product On My System But It Appears Not To Be There. I Have Never Had Any Symantec Products On My Machine And The Product Does Not Appear In My Startup File Or Indeed Anywhere Else I Have Tried. Any Ideas ???????
