"Snoopy": I don't know a free combination of spyware/antivirus/firewall, I use avg free for antivirus and anti-spyware(http://free.grisoft.com/doc/1). As a firewall I used Sygate, but during the search for an english download page I got informed that Symantec bought Sygate and stopped serving updates, so I might consider going back to Zone Alarm (http://www.zonelabs.com/store/content/company/products/trial_zaFamily/trial_zaFamily.jsp), also I didn't really like it..
