The term 'spyware' is not well defined. Generally it is used to
refer to any software that is downloaded onto a person's computer
without their knowledge. Spyware may collect information about a
computer user's activities and transmit that information to someone
else. It may change computer settings, or cause 'pop-up'
advertisements to appear (in that context, it is called 'adware').
Spyware may redirect a Web browser to a site different from what
the user intended to visit, or change the user's home page. A type
of spyware called 'keylogging' software records individual
keystrokes, even if the author modifies or deletes what was
written, or if the characters do not appear on the monitor. Thus,
passwords, credit card numbers, and other personally identifiable
information may be captured and relayed to unauthorised recipients.
Some of these software programs have legitimate applications the
computer user wants. They obtain the moniker 'spyware' when they
are installed surreptitiously, or perform additional functions of
which the user is unaware. Users typically do not realise that
spyware is on their computer. They may have unknowingly downloaded
it from the Internet by clicking within a website, or it might have
been included in an attachment to an electronic mail message
(e-mail) or embedded in other software. According to a survey and
tests conducted by America Online and the National Cyber Security
Alliance, 80% of computers in the test group were infected by
spyware or adware, and 89% of the users of those computers were
unaware of it. The Federal Trade Commission (FTC) issued a consumer
alert on spyware in October 2004. It provided a list of warning
signs that might indicate that a computer is infected with spyware,
and advice on what to do if it is. This new book helps shed light
on this insidious nightmare created by members of the human race to
wreck havoc on the remainder.
