I have to agree with you Doc, the tools that are available are no where near thorough and home/nonpower users will never get rid of everything with just a tool. That being said, I usually can get rid of "most" things with a combination of, Ewido, Counterspy, and HijackThis, and then make sure all hotfixes and service packs are installed.

Nail.exe is an interesting one. It has different versions which do different things. I think you may have mis-understood what I meant about that one . I've actually been able to get rid of it with a lot of tinkering, but I've not been able to figure out what program installs it.

The spyware that I had the nightmare with was one that installed itself as a system "boot" driver, which made it next to impossible stop, even in safe mode. Starting up in the command console was about the only way to disable it, but upon reboot, some other process was watching it and immediately recreated the file and added the process. Before I wasted any more time on that system, I wiped the box, so that one was one I never did figure out. I'd actually like to find it again to take the fight on again .
