Anti-virus is actually one kind of software itself which protects your PC from the viruses. Virus is also software program which takes over your PC secretly and run some unnecessary task. So anti-virus stop that program and make your PC secure from all other unnecessary work.

Antivirus is used to prevent, detect, and remove malware, including but not limited to computer viruses, computer worm, trojan horses, spyware and adware. Antivirus utility scans the files and Registry on your computer to detect and remove viruses and other malicious software. Its realtime component prevents malicious programs from installing or launching in the first place.

Computer viruses are software programs that are deliberately designed to interfere with computer operation; record, corrupt, or delete data; or spread themselves to other computers and throughout the Internet.
To help prevent the most current viruses, you must update your antivirus software regularly. You can set up most types of antivirus software to update automatically.

Antivirus is also a program which has libraries to protect your PC from latest viruses which can harm your PC. Its updated day by day to protect any latest virus which is become recently.

The Antivirus Action virus is among the countless infections that raid computers daily. This infection makes use of viruses like the Trojan horse to install itself onto unsuspecting computer systems; it attaches to computer systems via dubious downloads, fraudulent emails or any unsecured Internet access. Viruses feat neatly into the malware category of software - malware is just a shortened version of malicious software.

Almost all of whatever you articulate happens to be surprisingly legitimate and it makes me wonder why I hadn't looked at this in this light before.

Yes you are right and in 1988 new viruses and the possibilities of detecting and eliminating viruses were discussed by a mailing list named VIRUS-L[9] which was started on the BITNET/EARN network.It is basically a computer program that detects, prevents, and takes action to remove malicious software programs,such as viruses and worms.

thx fr your post, actually The first antivirus software was created in 1988 in order to combat the Brain virus, which originated in Pakistan.

Nice post. I am using Kaspersky antivirus software. It is the real time protection. It detects not only virus but also detects the worms, malwares and spywares.

Antivirus software is software that attempts to combat malware, such as computer viruses, computer worms, rootkits, and Trojan horses.

Antivirus software typically employs a variety of strategies, including searching for known patterns in malware executable code (signatures), and emulating a program in a sandbox to see if it acts maliciously. Success depends on striking a balance between false positives and false negatives. False positives can be as destructive as false negatives.

Antivirus software has disadvantages to the user as well. It often causes a significant decline in computer performance, it may present computer users with a decision the user may not understand. Antivirus software generally works at the highly trusted kernel level of the operating system, creating a potential avenue of attack.
There are two common methods that an anti-virus software application uses to detect viruses. The first, and by far the most common method of virus detection is using a list of virus signature definitions. The disadvantage of this detection method is that users are only protected from viruses that pre-date their last virus definition update. The second method is to use a heuristic algorithm to find viruses based on common behaviors. This method has the ability to detect viruses that anti-virus security firms’ have yet to create a signature for.
Many users install anti-virus software that can detect and eliminate known viruses after the computer downloads or runs the executable. They work by examining the content heuristics of the computer's memory (its RAM, and boot sectors) and the files stored on fixed or removable drives (hard drives, floppy drives), and comparing those files against a database of known virus "signatures". Some anti-virus programs are able to scan opened files in addition to sent and received emails 'on the fly' in a similar manner. This practice is known as "on-access scanning." Anti-virus software does not change the underlying capability of host software to transmit viruses. Users must update their software regularly to patch security holes. Anti-virus software also needs to be regularly updated in order to gain knowledge about the latest threats.
One may also prevent the damage done by viruses by making regular backups of data (and the Operating Systems) on different media, that are either kept unconnected to the system (most of the time), read-only or not accessible for other reasons, such as using different file systems. This way, if data is lost through a virus, one can start again using the backup (which should preferably be recent). If a backup session on optical media like CD and DVD is closed, it becomes read-only and can no longer be affected by a virus. Likewise, an Operating System on a bootable can be used to start the computer if the installed Operating Systems become unusable. Another method is to use different Operating Systems on different file systems. A virus is not likely to affect both. Data backups can also be put on different file systems. For example, Linux requires specific software to write to NTFS partitions, so if one does not install such software and uses a separate installation of MS Windows to make the backups on an NTFS partition (and preferably only for that reason), the backup should remain safe from any Linux viruses. Likewise, MS Windows can not read file systems like ext3, so if one normally uses MS Windows, the backups can be made on an ext3 partition using a Linux installation.

Virus are basically programs which are programmed to do some operation which is not desirable for the user.
Antivirus does the opposite,they monitor the programs doing those work and force them to stop doing the same.
Antivirus basically have more more processor power so that they can kill the virus which have less processor power.
this way they work.
