Ad-Aware does a pretty good job of detecting spyware or annoying adware. The program provides some real-time protection (removing spyware as it installs) and is better than average at finding hidden components. It is especially useful for IT or technical users. On the downside, it is more expensive than most other options, including our higher-ranked products and lacks some of the features you can get with said products. Also, the technical support was less than spectacular. You would be better off with a program that has the best of both worlds.
