Spyware
Programs that covertly gather user information through the user’s Internet
connection without the user’s knowledge. Once installed, spyware monitors
user activity on the Internet and transmits that information in the background
to someone else. Spyware can gather information such as email addresses,
websites visited, passwords, and credit card numbers.
Dialers
Programs that hijack a user’s modem and dial premium-rate phone numbers,
such as those required to access pornographic websites.
Password crackers
Programs that find passwords or encryption keys by trying every possible
combination of characters until the code is broken.
Adware
Programs that display unsolicited advertisements. Adware often includes
code that tracks a user's personal information and transmits it to someone
else, without the user's knowledge.
Potentially unwanted
programs
Programs such as viruses, worms, and Trojan horses that perform some
unauthorized (and often harmful or undesirable) act.
Key loggers
Programs that record every keystroke a user makes. They can be used to
steal passwords and other confidential information.
