From oldhermit - "So we are looking at less than an hour per week, in little 10 minute increments."

This comment says to me that what is needed is a little discipline each time you come up on your computer to spend a few mintutes checking out the computer. I had not thought of it in this manner. That would sure beats how much time a person spends on repairing their computer once it has been infected. (Look at all the help sites on the net working in this area.)

From mlh - "So I'm not complacent about Linux not being a target. But I feel a whole lot safer with Linux than with Windows."

It's nice we have a choice on what we can do. Here is a point though. Microsoft has 90% of the market. So if you were a cracker (that's the bad guys) and were trying to make a name for yourself would you target XP or linux? (Don't know why there was a difference in searching for Linux and Malware, but once you get above a half million what's another quarter million or so? We both made the point. )
