In the past, we used to queue at a bank for our banking needs, collect information from books, and operate offices with the use of complex paperwork and calculators, etc. But when computers evolved, man’s life was pretty easy. Computers are doing the math, managing queues, and doing paperwork more orderly, and that too on behalf of man. In today’s world, the computer has become a necessity for the proper functioning of our day to day. But we must not ignore the thieves and culprits who used to create a ruckus in our lives, be it in ancient times or in today’s scenario. Now, with the increase in the use of the Internet and computers in our daily lives, these culprits have acquired technological knowledge and are dedicated to creating software codes that, in one way or another, damage our computers. Sometimes these codes just consume our computer’s speed and slow down our work, but sometimes they are involved in damaging our files and useful information. These codes that create an uproar in our information technology world are popularly known as viruses.

Viruses are of many types and Trojans, worms, malware, botnets are some of the types of viruses found today that damage our computers in one way or another. Let’s not go into detail about what these viruses do on our computers, but let’s focus on how these viruses are caught and removed from our computers in a non-technological way.

The software code that is used to identify the viruses mentioned above is popularly known as antivirus. Almost all computer users should be aware of the importance of antivirus. But do we know how viruses are caught and removed from our computers?

These antiviruses are intelligently designed to detect the presence of known virus codes. I have used the word known virus code here for various reasons which will be discussed later in this article. But first let’s focus on antivirus first. These known virus codes are supplied to antivirus software by antivirus companies through day-to-day, hour-to-hour, or minute-to-minute updates. There are many antiviruses on the market and not all of them work the same way. When part of the virus code is ever detected on our computer, it is removed from our computers through the secure process of its removal. And this is the general operation of any of the antivirus available on the market.

Real operation of an antivirus

With the description given above, you would have had an idea of ​​how antivirus works. But we have used the known virus code word for a number of reasons that will be discussed here.

Whenever the research and development team of any antivirus company detects a virus that can cause problems for computers, they create a method to detect it and supply that code to the antivirus software through regular updates. Now, there is a question as to whether humans are involved in detecting virus codes and humans are also involved in creating new ones. There are always the presence of virus codes on the ends of computers that would not have been detected at all and these are the viruses that antivirus software does not detect at all.

Actually, whenever someone writes the code for a virus, they pay close attention to the fact that it should be on the computer undetected, and therefore many virus coders do not employ a harmful effect on the computer, but instead They do some kind of nasty. jobs like sniffing. And these are very difficult to detect even by some research and development team for a popular antivirus package.

According to one of the estimates, there are thousands of virus codes whose antivirus codes have not been written by any of the antivirus companies. And those are the viruses that do not harm the functions of our computers, but instead perform their individual work in the background of the infected computer process without being detected and removed by any antivirus software.

Should we use the antivirus?

The answer to this simple question is, of course. Since these antivirus software are capable of eliminating the most dangerous and detected antivirus from our computers and in this way offer security. It does not matter if the security is complete or not, but what matters is that there is some security software that is watching for virus codes that can prove disastrous. Having a little lax security is better than not having it at all.

Which antivirus is the best?

To address this problem, you must first simplify your needs. If you are using a standalone computer, you will be affected by a virus that can come from CDs, floppy disks or pen drives. For this you need antivirus software that offers at least offline antivirus solutions and these types of antivirus software are usually freely available on the internet and in abundance. But always search for the best through proper bulletin boards, news portals and other informational sources.

If you are using a computer for your online transactions or simply to visit a website, then another source of virus infection is activated. For these computers, the antivirus software must have the ability to strictly monitor the websites you are viewing for virus codes and must log off or display a warning message when they have any virus code on them. These types of antivirus software are sold at nominal prices and are available primarily from almost all antivirus software manufacturing companies. It is very easy to find the best of the sources mentioned above.

So find an antivirus that suits your needs and install it on your computer for your peace of mind, but always remember that there are always viruses that none of the antivirus packages can detect.
