A typical antivirus software uses
two techniques for the purpose for
securing the operating system.

Analyzing of files for detecting known viruses with the help of a
virus dictionary.

Identification of any suspicious behavior from any computer
application which might be a result of infection.
Other ways of detecting viruses.


Refers to a dictionary of viruses that have been known by the developer
of the antivirus software.
In case any code within a file comes in
agreement with the virus dictionary,
the antivirus software performs to either
delete that code or quarantines it so that
the toxin of it does not spread out to other
programs.
Files are examined when they are created, opened, closed or e-mailed.
Requires upgrading downloads in order to work successfully in the long
term.


This is a contrast antivirus application approach.
Its functionality is to monitor the behavior of the programs.
If an application is behaving to
write the data of another application
into an executable file, such an
action is considered as suspicious
and the user is immediately informed
by the software and prompt for a quick
and effective action.
Provides protection against those viruses also which are not
written in the dictionary.


Using a sandbox detection
method.
Emulating the beginning
code of every brand new
execution.
After the program is closed, the sandbox is analyzed
for any changes made within it in which an indication
of the presence of a virus can be made


Provides protection against
malwares and viruses.
Provides security to the
operating system in an affordable
cost.
Increases the performance of the
system.
Protection against latest virus definitions.


The basic function of antivirus software is to provide
complete protection against malicious software and
other virus definitions. Since, there are so many virus
writings created each day, many of the antivirus authors
are including several other functions within the program.


Threat Detection

Real-time Protection

Alerts

Automatic Updates

Additional Features


Scans the operating system
for all the major threats and virus
definitions.
This feature is quite
complicated in every other
antivirus as not all of these
software occupy full coverage over
these malwares.
Provides real protection from all the
incoming threats.
Moreover, if a system is not affected by a virus, this software must
still be obtained for preventing future infections.

Alerts when a malicious
program tries to gain access
within your operating
system.

Offers automatic updates
which means automated protection against latest virus
programs.


Many of the antivirus software offers some additional
features for the purpose of providing top most level of
security. These additional functions includes instant
messaging protection, e-mail protection, blocking of pop-
ups and identification threat protection.


Spywares: Spywares have the functionality of being
installed on the system without even being noticed
by the user.

Firewall: A firewall is considered as the most basic
defending tools against hackers or any other
unauthorized access to the system. Enabling the
Firewall within the system starts the system to
quietly monitor traffic which is incoming and
outgoing from the system


Browser Security: Many of the hackers, virus creators
and cyber criminals finds weaknesses within the web
browser and adopts the habit of capitalizing this
opportunity.

Phishing Protection: This type of a threat takes place
in the form of a two-way attack which starts from
sending fake e-mails pretending that the source of
the e-mail is genuine.


Parental controls: This is a program through
which you can limit the use and in many cases,
monitor the computer ukase of specific users.

Spam Filter: This utility performs like a sieve and
is also known as anti-spam software. Its
mechanism is that it passes on legitimate e-mails
from contacts but blocks the access of unsolicited
e-mails to your mailbox.


Computer users have unlimited choices when it comes to
the selection of antivirus application. There are free trail
offers ass well as purchased software which can be easily
obtained from the web. Despite of the quantity, it is still
a very daunting task to select as to which antivirus will
work best with your system.


User-friendly Interface.

Effective identification
and elimination of viruses.

Quick scans.

Frequent updates of virus definitions.


The protection of your system does not lies in the
actions of cyber criminals but it rests within your
own hands. Install antivirus software and keep
your system protected. Good Luck!
