In addition to this, there are various institutions that maintain all their employee information or student records on a computer. Basing an entire project on software makes it easy to operate, due to ease of collaboration, ease of data transfer, quick edits, etc.

However, one major problem that arises out of this scenario is the safety of all this information? What guarantee is there that our processes will not be hacked and hijacked midway.

What guarantee is there that all the records of the students of a particular school will retain its integrity and no one will try to break into it to manipulate that data?

This is where antivirus software comes into use. Antivirus software is those programs that are designed to prevent and protect a user from malicious software, such as Trojan Horses, Worms, Viruses, etc.

They are used to maintain the integrity of data and ensure the smooth, safe, and secure flow of events virtually.

Norton and Bitdefender are two major players in this antivirus software industry, and both of them have a wide userbase, as well as deliver promising results.

What is Norton?

Norton is one of the leading antivirus software programs in the world. This program has been developed and maintained by NortonLifeLock since the year 1991.

This program has been a part of the Norton family since then and has evidently received a lot of attention and market share, which ultimately helped it become one of the best virus protection software out there.

Norton has a carefully prepared system of signatures and heuristics which it uses to identify and block viruses.

Other than protecting a computer from different kinds of viruses, it also provides some other features, such as spam email protection, scanning of downloaded documents, safe web search, etc.

The Norton Antivirus Program was so popular, that back in 2007, it held for about 61% of the market share, and even at that time, some of its major competitors included Kaspersky, Bitdefender, etc. 

In order to increase usability, and support across all domains, Norton is available for Linux, Windows, as well as macOS. This is particularly useful for a major antivirus company when they are trying to grasp a major share in the market, as this tends to the needs of all kinds of users.

In addition to cross-platform support, it also has various packages across different price ranges, which one can choose from based on their budget and needs. Initially, though, it was only for the Macintosh, for which the company Symantec made an antivirus.

When Symantec acquired the Peter Norton Computing company, then they used their technological resources and Symantec’s antivirus program to create the Norton Antivirus Program.

What is Bitdefender?

Bitdefender is a Romanian Antivirus Company, that was founded back in 2001 by Florin Tapleș. Ever since then, Florin has remained at the position of CEO, and now the company has over 1600 employees.

A lot of people find the rise of Bitdefender a really inspiring story, as the company started in a country which did not have much of a software market share, especially in 2001, and then it went on to become one of the most successful antivirus programs created.

According to 2018 statistics, Bitdefender currently has 500 million active users, which easily puts it on the list of one of the most popular antivirus software used.

Originally Bitdefender was called SOFTWIN and was branded and marketed as an AVX (Antivirus Expert). It was only in 2001 when the name of this software was changed to Bitdefender.

Bitdefender did not just limit itself to antivirus software but branched out to other cyber protection technological solutions, such as Bitdefender BOX.

Basically, the Bitdefender BOX is an internet of things (IOT) protection device, which monitors all interconnected devices, and keeps viruses from the internet away from the system.
