Spyware

SPYWARE

Spyware is an application that
gathers information from a
person's computer without
their knowledge or consent. It
is also known as a spybot or
tracking software. Spyware
applications are usually used
to send spam to unsuspecting
users. The easiest way to install
a spyware on a users system is
through pop-up windows,
freeware applications or
screensaver packages.
Applications that install themselves
through advertisements
are called adware.
But since marketing companies
raised objections to
the term adware, the
Internet security companies
also refer to such
applications as "potentially
unwanted programs" or
PUP in short.
