Take Control of Spyware and Adware

Install a good antispyware tool - but watch out for antispyware scams. The Web is rife with "antispyware" tools that do little or nothing to prevent spyware, and some even make it worse. Make sure you get your tool from a trusted vendor.
Be selective about what you download. If you don't have a reason to trust the company providing a piece of software, hold them to increased scrutiny. Visit their Web site to learn more about the people behind the technology, as well as the technology itself.
Read licensing agreements. Don't just scroll to the bottom and click the "I accept" button when installing freeware. Instead, read each agreement carefully and look for language pertaining to information-gathering activity.
Beware of programs - especially free ones - that flash clickable ads in the user interface. Their presence is a red flag, and it's possible someone is watching how you respond to them.
Disable scripting and active content unless you really need it. Scripts - especially ActiveX controls - are common tools for installing spyware without your knowledge or consent. You can always turn on scripting should you need it for a trusted site.
