Stop looking at pr0n!
I know you're probably looking for something a little more hard-core, such as something you gotta pay for, but I use some freebies that keep them keyloggers, etc.. off my machine such as
Spybot S&D, and
ClamWin.
I'm sure they won't fit your needs though because like I previously said, you're looking for software probably. But those are some free ideas.
