One has to take the right decision while dealing with those prompts as a single wrong decision can lead you to a security break.


History of Antivirus

It was in the 1980s when the majority of the computer viruses were written.

Those viruses were supposed to be limited to self-reproduction.

Those viruses were written in such a way that no specific damage routine built into its code.

But as more and more programmer became familiar with the virus programming.

Such a way that they could be manipulated and pretty much capable of infecting or destroying the files stored on an infected computer.

There are so many competitors who claim for being the first to introduce the antivirus product.

However, it is believed that Bernd Fix was the first who performed the publicly recognized removal of the computer virus in 1987.

In 1984, Fred Cohen published the first academic papers on computer viruses.

Later, he indulged himself in developing strategies for antivirus software in the year 1988.

The purpose of this mailing list was to discuss the new viruses, their detection, and elimination.

Two major names John McAfee and Eugene Kaspersky were the members of this mailing list at that time.

And both of them develop their own software companies.


These are still developing and selling antivirus software.

Before the evolution of internet connectivity, the major source of computer viruses was the floppy disks.

At that time, virus checkers check executable files and the boot sectors of floppy disks.

How Virus Increased

The viruses began to spread more quickly with increased usage of the internet.

This allowed the viruses to spread online rather than any other device.

Now it has become inevitable for antivirus software to check a maximum number of files than confined to just executable files for a number of reasons.

  • As we all know that word processor applications like Microsoft Word make use of powerful macros.
  • Virus programmers use macros to write virus set within documents. By doing this, they verified that whenever the infected file opened, the virus could infect the computer.
  • The second reason involves the email programs, especially Microsoft Outlook Express and Outlook.

Nowadays, internet broadband is common in each and every house.

It is, therefore, necessary for all internet users to update their antivirus software regularly to prevent any major damage to their computers.
