Hi I've been reading a lot on how rare it is to have your mac being a victim of spyware but I'm just so paranoid that I need you to recommend me some kind of spyware scan, preferably free.. tried MacScan demo but reviews say that it's not very good. What causes my concern is that last night, someone sent me a few files and I've opened them and saved them. Even though I know this person, I regret doing that but I just have a hard time saying no to people so I downloaded them. This person knows that I've this system and basically is a genius when it comes to everything so there is a chance that my mac has spyware now, isn't it? Can you please help me check?
