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 they made man’s life quite easy. Computers do the math, manage the queues, and make the paperwork more orderly, and that too in the name of man. In today’s world, the computer has become a necessity for the proper functioning of our daily lives. But we should not ignore the thieves and criminals who used to create a ruckus in our lives either in ancient times or in the present scenario. Now, with the increased use of the Internet and computers in our daily lives, these culprits have become technologically savvy and are dedicated to creating software code that, in one way or another, damages our computers. These codes sometimes only eat up our computer speed and make our work slower, but sometimes they are involved in damaging our files and useful information. These codes that create a ruckus in our world of information technology 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 to 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 they catch viruses and remove them 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 several reasons that will be discussed later in this article. But first let’s focus on antiviruses first. These known virus codes are supplied to antivirus software by antivirus companies through daily, hour-by-hour, or minute-by-minute updates. There are many antiviruses on the market and not all of them work in the same way. Whenever any part of the virus code is detected on our computer, it is removed from our computers using the secure removal process. And this is the general operation of any of the antivirus available on the market.

Actual operation of an antivirus

With the previous description, you will have had an idea of ​​how antiviruses work. But we have used the word known virus code for several reasons that will be discussed here.

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

In reality, whenever someone writes a virus code, 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 disgusting. jobs like sniffing. And these are very difficult to detect even by some research and development team of a popular antivirus suite.

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 computer, but are dedicated to doing their individual work in the background of the infected computer process without being detected or removed by any antivirus software.

Should we use the antivirus?
The answer to this simple question is yes, of course. Since these antivirus software are capable of eliminating the most dangerous and detected antivirus from our computers and thus offer security. It doesn’t matter whether the security is complete or not, but what matters is that there is some other security software watching for virus codes that can be disastrous. Having a little security is better than having nothing.

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 flash drives. For this, you need an antivirus software that offers at least offline antivirus solutions and these types of antivirus software are often freely available on the internet and in abundance. But always search for the best one through suitable bulletin boards, news portals and other informative sources.

If you are using a computer for your online transactions or simply visiting 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 code and must log you out or display a warning message whenever they receive any virus code. These types of antivirus software are sold at nominal prices and are mainly available from almost all antivirus software manufacturing companies. It is really easy to find the best from the sources that have been mentioned above.

So find an antivirus that suits your needs and install it on your computer for peace of mind, but always remember that there are always viruses that cannot be detected by any of the antivirus packages.
