Anti-Spam Software for Mom?

daemondev asks: "As a software engineer and FreeBSD user, I've had no problem setting up and using the early anti-spam solutions like Spam-Assassin, TMDA and PopFile. I'm reasonably happy with where I am today, but it certainly could still be better! On the other hand, these solutions are not at all appropriate for my mom, who now has a huge spam problem (she really doesn't need all of that Viagra). I'm looking for something that works "out of the box" and doesn't require a lot of in depth knowledge about email and text filters, and which ideally doesn't need to be updated and replaced continuously. She uses Outlook 2000 on Windows ME. Has anyone found a good package that they would trust to stop spam but that's easy enough for their mom to use?"
