What are the useful tools form that site to run on Windows, besides the obvious ones like Spybot and Spyware Blaster? Thanks for any input.
A few of the good Windows security tools:
Cain&Abel, Netstumbler, Pwdump, nmap, ethereal(aka:wireshark not mentioned), Metasploit Framework, the sysinternal suite(not mentioned),tor, and nessus(not mentioned).
I'm sure there are many others that can be used in Windows. Those are just a few I could think of off the top of my head.
A web search will lead you to their download page.
