PC Magazine reports: "The term spyware is actually a catch-all for a variety of nonvirus malicious software (malware, for short). Trojan horse programs masquerade as something useful—games, screen savers, utilities—but actually have their own sneaky agenda. One especially pernicious type of Trojan pretends to be an antispyware utility. These rogue antispyware programs tend to be alarmist, reporting tons of threats and offering to remove them—for a price. The term adware refers to programs that display ads on your computer (independent of the built-in banner ads on Web pages). Spyware literally spies on you, gathering personal information and sending it to the lair of its evil creator. Keyloggers specifically records all the keys you type, thereby capturing passwords and other sensitive info. Some of these may use rootkit technology to escape detection. A good antispyware program will handle all of these overlapping threat categories."
