We can safeguard our system using updated Antivirus
software. Antivirus software prevents our system from any
internal and external bugs, viruses, worms, Trojans,
corrupted data and also damaged files. This software ensures
that the system is virus free and also that there is no harm
using any file/information/data. 

Key Benefits of using AntiVirus software

Automatic Virus Removal:
An Antivirus automatically detects and eliminates all types
of viruses quickly and effectively. After selecting the
drives to scan, any infected files it encounters are
detected and disinfected.

Real Time Virus Protection:
The on-access virus scanning feature in an Antivirus means
that all files are automatically checked for infection at
the point of user interaction. If you open, move, copy or
update any file, the On-Access Monitor will instantly
analyze the file before it is opened. Antivirus also
continually scans memory resident processes for viruses. If
you launch a program or file which creates destructive
anomalies then the scanner will detect it. Such instant
detection of viruses assures you that your system is
perpetually monitored for threats.

On Demand Virus Scanning:
If you suspect a file, disk or folder may be infected you
can use the on-demand virus scanning feature of Antivirus to
perform an instant check on the selected object. On demand
virus scanning is seamlessly integrated into the Windows
operation system. Users can scan specific objects 'on the
fly' by simply right clicking on a file, folder or drive and
selecting 'Scan with Antivirus' from the context sensitive menu.

Protects Against Unknown Viruses:
Antivirus employs the latest techniques to identify
previously unknown viruses and Trojans. If it be found any
virus so then Antivirus will disinfect the file or recommend
it for quarantine.

Enhanced Archive Virus Scanning Functionality:
A powerful Antivirus also scans archived files such as .zip,
.rar etc. You will be alerted to the presence of viruses in
compressed files before you even open them. These include
RAR, WinRAR, ZIP, WinZIP ARJ, WinARJ and CAB archives.

Wizard Based Daily Updates:
Every time Antivirus is started automatically checks the
date stamp on the virus database. Available updates are then
automatically downloaded and integrated into the existing
database.

Quarantine Suspicious Files:
The quarantine facility removes and isolates suspicious into
a safe location before analyzing them for possible
infection. Any files transferred in this fashion are
encrypted- meaning they cannot be run or executed. This
isolation prevents infected files from affecting the rest of
your PC.

Minimum Drain, Maximum Virus Protection:
Antivirus offers perpetual and effective virus protection
for your PC yet hardly touches system resources. It will
quietly defend your system from virus attacks but won't hog
your CPU or RAM. Antivirus unobtrusively sits in your system
tray whilst affording complete virus protection.

User Defined Scheduled Virus Protection:
Antivirus now features a highly customizable scheduler that
allows you to timetable scans according to your preferences.
You can choose to run scans on a specific object at a
certain time on a daily, weekly, monthly or custom interval
basis. Perhaps you wish to check your entire system first
thing in the morning; maybe you prefer the middle of the
night! Antivirus gives you the power to choose.

NOTE:
This should be cleared in mind that Antivirus software is
updated with current virus definitions and is registered
version. Antivirus software is user friendly and each module
of the antivirus program can be easily accessed and
configured from a single, centralized, location. The system
status screen provides an immediate 'heads-up' summary of
Antivirus' current configuration.
