I found "Perfect Keylogger" installed on my box a few days ago. Turns out Norton AntiVirus 2003 doesnt class a keylogger as a threat, so it had lain undetected for about a month, in operation.
The only thing that could find it was AdAware 6, and a prompt upgrade to Norton AntiVirus 2004 removed it for me. Changing all my passwords was quite a boring task, and I'd assumed I was safe with spyware/antivirus and a firewall...
Keeping a hahahahahahas PC secure on the net is time consuming these days
