NAV2009 AntiSpyware OK?

Since SpySweeper will not work now with NAV2009, is the AntiSpyware built in to NAV2009 good enough? I have a 3 user copy I bought a while back, but have not installed it yet. Since my SpySweeper has now expired, I wanted to know if NAV2009 was good enough? If more is required what is good and plays well with NAV2009. Freeware is good too.  :-)

 

TIA
