What is the difference in Spyware and Adware?
Spyware programs actively record user information and return that information to it's creator without the user's consent. Spyware is often malicious, intrusive, and destructive. Some spyware programs will even download and install other spyware programs or viruses.
Adware is often bundled with "freeware" or "shareware" programs that are available online, and is usually installed with a user's permission. Many "freeware" or "shareware" programs include Adware to pay for program development. Having the adware installed is considered the trade off for use of the free program. Adware is similar to Spyware in that it does collect personal information to send back to its creator.
