The Importance of Antivirus Software


The importance of having antivirus software on your computer is crucial. Have you ever lost extremely important documents due to computer viruses and corrupted data? Maybe yes, maybe no but regardless, it is important to always keep yourself ready in case of viral attacks being made against your device.

The importance of antivirus software is largely forgotten by many. However, this is a necessary investment, since it protects you from losing data from corrupted files or from hackers. These virtual terrorists pose a serious threat to your finances and online identity.

One of the most common reasons for failures or problems in computers is the lack of antivirus software, or expired antivirus software. It is an issue which is often overlooked and has dire consequences for the unfortunate computer owner.

What is a Virus?

These days there are so many different types of virus. So, what is a virus? A virus is usually hidden and can do a number of things, as it relates to the health of your computer. A few examples are provided below:

  • Makes a computer run slowly
  • Prevents computers from booting up
  • Damages parts of the system or amend how the system operates without the owner's knowledge
  • Be used to steal personal details
  • Move from machine to machine on a network
  • Attack other machines using a machine as a host
  • Send out unauthorized messages or emails

So, like a human virus, a computer virus can be dangerous and possible infectious to other computers. They can be spread between computers and also be transported via email. It is not limited to software however, as they can also be transported via USB drives and other types of media.

Where Does a Computer Virus Come From?

Computer viruses are usually malicious computer programs written in order to damage other people's machines or steal information or even cash. God knows, why these malicious hackers invent these things, even the thought is beyond me! They are usually highly skilled programmers who have decided to use their skills in a negative manner.

Some viruses are written as an “ego” boost. In other words, some programmers write these things just to prove that they can hack into a major site or obtain private information. However, there are also criminal programmers who have a much more devious intention. Grrrrr

What Types of Virus Are There?

Sometimes the definition of what constitutes a virus is not clearly defined. In general, a virus almost always damages files on a computer. Some other types of malicious software such as spyware are used to steal information from the user but may not damage the computer.

I had this dreadful experience several years ago where I got a phone call from a “so-called” employee from Microsoft. He convinced me that I had a problem with my computer and asked permission to “dial in” to fix it!

Well, you can guess what happened can't you? Yep, he must have installed a horrible virus which caused absolute havoc with my computer. The problem was that bad, that the computer repair man could not get rid of it, no matter what he did. My computer was trashed and ruined. He had to sell me a second hand computer, which was virus free.  I then had to start from scratch.  I'd lost everything, bar from what I'd already backed up previous to this overseas hacker's phone call.  That was a lesson well learned I can tell you!

Types of Virus include:

  • Worms – These are programs which copy themselves to other computers on a network. They tend to slow things down as they consume more and more bandwidth or computer resources.
  • Trojans – Performs functions (sometimes malicious) on the computer without the knowledge of the user (think of the horse of Troy)
  • Malware – Technically, this is not classed as a virus. It is software used to spy on computer user's activities and collect personal information. More commonly known as “spyware”.

What Does Antivirus Do?

Antivirus software is the “policeman” at the gate of a computer system. It protects the computer from incoming threats and seeks out, destroys and warns of possible threats to the sysstme. New viruses are coming out all the time. It is the job of the antivirus software to keep up with the latest threats. This is achieved by daily updates of the antivirus database definitions, which counteract the latest threats to provide constant protection.

Antivirus Software is Vital!

Not having antivirus on a computer is like inviting a criminal into your home or having an uninvited guest! They then cause havoc or steal from the owner. Today's internet has provided many ways for virus attacks and there are thousands of threats. To be safe from these, it is vital to police the computer and have it protected at all times. The importance of antivirus software cannot be underestimated, as I found out many years ago!
