My friend at work has a mom who has an old imac running 8.6. And since he doesn't know to much about macs, and I seem to be the mac expert at work he came to me with the question of what to do about: classic mac os virsus, spyware, browser hijacks, defrag. Is there any freeware that can help with these thing? I have no clue. I switched into OS X, and have never needed to use classic for anything. Any help would be great!
