AlertSpy software from AdwareDeluxe acts like antivirus tools. It maintains a library of spyware filenames and registry keys, searching for and removing them from your computer.

Adware offers varying degrees of annoyance. Some adware merely delivers a small ad banner in a program's interface, such as the ad displayed in ICQ. Other types of adware launch pop-up browser windows over pages you're currently viewing. The worst kind of spyware gathers personal data about you and sends it to a central server.

Adware Deluxe supplies immunizers that prevent known adware from installing and hold off suspicious program installations. When you install programs, make sure to read all the installer screens, especially the license agreement.

Your PC is probably infected if:
You have downloaded free mp3 music online using P2P.
Your computer is running extremely slow.
Your computer is invaded by those horrible popup ads.

Programs designed to deliver ads or to get marketing information is considered as adware. Spyware is a subset of adware, focused on reporting personal information.
