I was wondering about the files Im downloading, some of them are program files and after I unzip the files on my G4 I am getting a file called Setup.exe
Whats with that? Is that some type of virus your discussing before? Its not anything I can use.

Yup, it's spam. If you were on Windows, you would 9/10 have a virus. Luckily your on a mac, so your safe. lucky. But if your not downloading any kind of program, add those keywords to your filter.
