My standard spyware security set-up involves installation of both AdAware SE Personal ( http://www.lavasoftusa.com/software/adaware/ ) and Spybot - Search & Destroy ( http://www.safer-networking.org/en/download/index.html ). Make sure to also download the latest updates for each (or you can update from within each application after installation). I also like to use the free version of ZoneAlarm as a firewall ( http://www.zonelabs.com/store/conten...try=US&lang=en ) - the Pro version isn't worth the $$$$ or hassle for a home machine. Add to those any good-quality antivirus, keep them all updated, browse carefully, and you should be 99% safe from malware.
