Hello Donna,
I am not aware of any, probably because I have not looked. A number of Windoze IE faults are not available (thank god!) on the Macintosh because of the differences in hardware and software.
It is very true that the spyware is not considered a virus, so traditional virus utilities will not recognize it as such.
Is there anything happening on your computer that is causing you to look for such a utility?
Thanks,
Christian
