Adware and
Spyware
Adware is any
software application software which makes banners appear the whole
time it is in function. Also, the adware program can install
components that will transmit information about the user and its
behavior and this work on his PC. Unlike spyware programs, the
user is asked when the program is being installed. Actually, an
adware application is the application that, along with its basic
functionality, has a different one, the one that makes it show
commercials once in a while, downloaded periodically from certain
internet servers.
Spyware is a
program, usually downloaded from the internet, which sends
information about the user without him knowing it, every time he
connects to the internet. Usually, the packages sent contain
marketing information and not confidential information, although
some programs can do that too.
Even if some
applications are both adware and spyware, this is not a generally
true situation. Most of the times spyware applications have
installed themselves and they are working without the user knowing
it, opposing the adware applications that cannot be installed
without the consent of the user.
For a long time
quality and free software was installed and used for free but once
the complexity of the programs became greater their costs have
risen till the point the developers just had to find out methods
to diminuate them. One of the easiest ways was delivering along
with their programs application like adware and spyware. On the
other hand, many commercial programs became usable freely and
legally by passing the line to the adware category.
From the
harmless intention of showing some commercials and till elements
of analyzing and stocking information about the user and his
software or hardware configuration the developers had to install
on the target computer supplementary modules. If at the beginning
it was only an engine that downloaded commercials and showed them
in pre-calculated windows, the adware industry has evolved and
grew a great bit since then. Now they use different instruments,
from altering your browser and its settings and till launching
background applications that monitor your PC activity.
