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.
Among the effects that follow installing spyware
and adware are the next ones:
-
Adding links to various magazines
-
Adding new commercials on the web pages,
sometimes replacing the existent ones
-
Monitoring browser behavior in commercial
purposes.
-
Gaining access to passwords and credit cards.
-
Slowing down the computer.
-
In some cases they can call telephone numbers with
high costs.
-
Changing the browser’s homepage in commercial
purposes.
-
Strange icons and new software might appear on
the desktop.
You can enter their online sites and try the services for free, then
decide what to use.
