What Spyware/ Adware Removal tool is compatable with Windows Vista 64 bit?

I have recently been downloading trials of these tools, but everytime I try to install them, I get a error message saying that the program is only compatible with 32 bit windows, not 64 bit. I tried searching online for 64 bit compatable programs, but the search engines bring up the programs that I have already tried to run.

I believe Spybot is vista 64 bit compatible now
