ANTIVIRUS SOFTWARE

ANTIVIRUS SOFTWARE

ANTIVIRUS SOFTWARE refers to applications designed to detect and remove viruses from computer systems. Antivirus software is a computer program that is used to protect our computer system against unwanted virus attacks. It scans computer memory and mass storage to identify, isolate and eliminate viruses.


It also examines the incoming files for viruses as the computer receives them. It is like a doctor for the computer at programs that diagnosis the patients and makes them fit.


FUNCTION OF ANTIVIRUS
There are several different companies that build and offer anti-virus software and what each offers can vary but all perform some basic functions:


Scan specific files or directories for any malware or known malicious patterns.
Allow you to schedule scan to automatically run for you.
Allow you to initiate a scan of a specific file or of your computer or of a CD or flash drive at any time.
Remove any malicious code detected. Sometimes you will be notified of an infected and asked if you want to clean the file other programs will automatically do this behind the scenes.
Shows you the ‘health’ of your computer.
But having Antivirus software in your computer does not guarantee 100% protection, as the installed antivirus program would not be able to detect new virus programs. You should keep on updating your computer with the latest versions of Antivirus programs. Most of the Antivirus software companies provide the facility to download the latest updates from their websites.


Most companies firstly make the virus and then after some month they provide antivirus. Now-a-days companies spread virus and also provide solution. This is common way of business.



The most popular anti-virus software available is Quick Heal, Kaspersky, McAfree Antivirus Software etc.
