to the people who are not clueless;
I do not think having more than (1) anti- virus / spyware / adware whatever is a bad thing. In fact, it is probably better to have (2) BUT , only one running at a time. Having 2 different programs can catch more "bad stuff" than just utilizing one program. On many occassions I have ewido find things my main defender program does not pickup and vice versa. The main point here being make sure only one application is running. Never both programs.
For what its worth.
