Downloading Google Earth from the Google website will introduce no viruses, I'm sure of that. I'm equally sure that Norton isn't the best thing to use on a Mac. I've tried most of them and VirusBarrier seems to take the cake for me. Admittedly I didn't try Kaspersky Lab United States | Antivirus Computer Security before I committed to VirusBarrier (although that is the one I use on my PC).

Nice that you cleaned up the Mac, tho. Not good having nasty critters running around. Not that it would have infected you but, possibly, you'd have given it to someone else on the less-than-useful-operating-system called Windows.
