Need some advice

Hi,

 

Just bought NAV 2009 gamer's edition. Need some advice on installation.  I owned NAV 2006 and decided to buy NAV 2009.  I run windows XP with service pack 3.  I  have read that norton clashes with Spybot S&D.  I also have teatimer running. Do i need to uninstall spybot or just need to disable teatimer?  I have also install spywareblaster. 

 

Thanks in advance !!
