Does anyone use a program, or know a program to scan for these on a Mac. I know OS X is "virus proof" but I do know you can still be affected by spyware and the like. Which programs do you use, if any, and what do you recommend that is cheap or free. I know with Mac's you basically have to type in your Admin password to install it, and common sense always helps, but just in case, I'd like to have a Spyware remover as a back-up. Thanks!
