What Does Virus Protection Do?

Living in the 21st century, an unforeseen threat has surfaced which had hardly been conceived earlier, that of cybercrimes. With the rapid evolution of the technology and continuously increasing dependence of the common public on it, the loopholes in them have become a grave matter for concern.

That, in turn, has brought up something new and vital in the picture, Cyber Security. The term could stand for multiple practices, processes, etc. which are designed to protect networks, devices, data and programs from damage, attack or any kind of unauthorized access. Here, in this article, we will discuss the necessities of virus protection.

Virus Protection and need

If you use your computer regularly, then you must be acquainted with the word virus. But many of us may not know that a virus is just a compiled application, which we often unknowingly run on our computers. Anyone who is capable of programming computer software can make it.

The only thing that makes a virus different from regular software is the fact that it is meant to harm your computer by deleting data (which at times may be vital), crashing your computer, or even steal valuable information from your computer. All this can make you or any user for that matter feel vulnerable.

However, you need not worry about the security of your computer if you have virus protection installed on your computer. Virus protection is a subset of cybersecurity.

A virus protection software is designed so as to prevent worms, viruses and Trojan horses from getting into a computer and even annihilate any malicious software code that had already infected your computer.

Most of the virus protection utilities are now bundling anti-malware and anti-spyware capabilities to go along with anti-virus protection. Not only this, the internet security suites are going a step further and including other capabilities like anti-phishing, file protection, PC optimization, firewall, and anti-spam.

How does it work?

To understand how virus protection works, it is vital to understand the working of a virus. Since a computer virus is just a compiled application, it is made up of bits like any other.

If the code of the virus does not change, it will get compiled into the same sequence of bits each time. This sequence of bits is often referred to as the ‘Signature’. As the signature of that virus never varies as it moves from one computer to another, it creates a footprint.

As the signature remains the same for that virus, anti-virus vendors store this signature to recognize this virus when it is stored on a computer. Anti-virus software makes use of a database of these signatures and checks all the executable files and matches them against the database.

However, sometimes it might be difficult to track a virus that may put your cybersecurity at risk. In these cases, people use variants to add on to the existing virus signatures. Since the new variant has originated from the original virus, its signatures are only slightly different and can be identified.

Since new viruses keep on emerging, these databases require updates. To enforce the cybersecurity of one’s computer, the software should be regularly updated.

Wrapping Up

In recent times the need to enhance the cybersecurity of one’s computer has increased a lot as people are now making use of new technologies more than ever.

We are storing our account details, important documents, personal journals and that’s just the tip of the iceberg.  To make sure of one’s cybersecurity, making use of virus protection software is a small but vital step.
