As a result most households at least have one computer in the form of desktop or laptop computers. Companies also keep upgrading the software applications and hardware to improve computer speed. But innovations also come with its own set of challenges. With continuous upgrades in the software industry the attacks on computers are also growing.

The core objective is to protect computers from viruses and hacking. You can do it using many ways and the use of antivirus is one of them.

What is antivirus software?

As the name suggests, this is a small software application that protects a computer from getting infected. Same as we humans, computers also get sick and need treatment. In humans the viruses are in biological form. In the case of computers the viruses are digital.

Who creates a Virus and Why?

There can be many answers to this question. Everything depends on what kind of answer you are looking for. Check out these conditions where a virus may exist.

First of all the primary objective is to steal valuable data and information. Hackers want to get into your system without your knowledge. Therefore, they write a software program to hack. It can be in the form of a link or they may ask you to fill a form.

The second world is of individual hackers who do it for fun. They want to corrupt your computer just to prove their knowledge. Sometimes they hack your system and demand money to give back control.

Companies create viruses to sell antivirus software applications. It is like a normal demand and supply principle. If there is no demand there will be no supply. Companies want you to buy their software applications. As per one of the estimates, the antivirus software industry is more than $4 billion. Due to this they hack computers and send trojans etc. later their software cleans the system and you start believing in their value.

Governments create viruses to hack computers in competitor countries. They want to steal valuable information for strategic use. Not only this in some un-democratic countries, governments spy on their citizens to suppress any revolution against them. Pegasus is a good example which was created to hack cell phones of various important personalities. Many governments buy the software for political reasons.

The software that suits your computer is the best. I say this because irrespective what antivirus software you have in the PC it can get hacked. If you are running a business, protecting information is important. You simply cannot rule out the possibility of viruses in the system. But installing antivirus software surely helps.
