Choosing the Right Product
The question you probably have after all of this is "Which program should I install out of all the ones that are available?"
Okay, let me amend that slightly: I'm not asking you to spend $50 apiece on three or four different anti-spyware utilities. But there are enough free products available that you can run two or three products without breaking the bank. And in many cases, you'll find that each of these programs will find spyware infections that the others won't. For example, I've run a scan on my personal laptop with each of these three products in the last 60 minutes, and each one has found a spyware threat or infection that the other ones missed. So, if you're serious about keeping your home computer free from spyware, you should run scans with at least one of these products, and preferably more than one to make sure that nothing falls through the cracks.
