Do Macs get spyware? On a Windows comp, you can get spyware just by going to the wrong sites (have you ever tried www.thesun.co.uk??), as well as from using things like Kazaa (not Kazaalite). However, you can get Ad-Aware 6 for Windows absolutely free. I've never thought about it, but is there free software that checks Macs for spyware? Can the same spyware that infects Windows computers also infect Macs? I wouldn't think so, but I just want to double check.
