As humans contract diseases, so also computers contract viruses. The way a computer is infected with virus is quite not far fetched, as it hinges on the user’s day to day computer activities.  A computer virus is a program designed, to move from one computer to the other for the purpose of altering the way a computer operates.

When virus gets into a computer, it does not serve good function to that particular computer rather it cause damage. Computer viruses are normally created by unscrupulous elements to move from one computer to the other. When getting into your computer, they may perform the damage that the creator of the virus want the virus to do.

That is, viruses when it infects a computer, it can corrupt files, steal relevant information on the computer or even money, spam emails, some viruses may even go as far to wipe off relevant information on the computer.

For a virus to get into a computer, it depends on the activities embarked upon on the computer by its user or operator. How? This is what I will be discussing below.

In this technological advanced world, let us imagine the amount of computer users and the amount of activities being done on their respective computers.

In the course of engaging in these activities in their respective computers, they will need data and information, send information and data, process data to information, save data and information etc. which makes the invasion of virus or viruses feasible.  These are ways in which your computer can be infected with virus:

1.         Electronic Mails (Email)

Email is one of the ways for virus to spread. How? When one receive a mail and there is attachment or link which is corrupted with virus. If the user clicks or opens this link or attached.

It may even be from a friend, family member or a colleague at work or school who may not be aware that his or her computer is corrupted and virus may spread through this process.

So before you open an Email, always be careful and ensure you scan necessary attachment and links that comes with the email with your antivirus software or email provider. Also, put it in mind not to open unexpected emails.


Virus can invade and infect a computer while downloading from the internet. A computer virus will not write on itself that ‘Beware, I am a virus do not click on me’. Viruses are mostly attached to software, files, packages, links, videos, music even websites in form of camouflage.

It is only when a computer user set up a parameter of preventive measures that one can notice. This can be achieved through installing an antivirus software to perform scan on downloads on completion.

Before any download from the internet, always ensure to check if it is from a reliable source and ensure to read relevant information attached to the download package to be well sure.

3.         Social Media Scam Links

There is always a great trust placed on social media. The aim of masterminds behind the creation of different social medias is good but it seem unscrupulous users have diverted the purpose to suit their dangerous whims and caprices.

If we check the rates of atrocities that have been performed on various social media platform so far, it certainly calls for attention to be careful.

Atrocities ranging from bullying, fraud etc. Most viruses invade the computer through social media means, such as messages, links, advertisements sent on these platforms and so on are forms through which virus can invade your computer.

4.         Infected Drives, Discs and Disks

Imagine if Peter’s computer is corrupted with virus and Paul needed to copy a file in his computer. Paul has no other means than to use his flash drive.

Unknowingly to Paul, the fact that Peter’s computer has virus, Paul copied the file using his flash drive and inserted in flash drive in his laptop with the aim to transfer the file from the flash drive to his laptop which but Paul’s laptop has no rock-solid antivirus software.

After transferring the file, one could guess what would have happened to Paul’s laptop.

From my illustration above, the same process of transferring virus applies to disc and disks. This kind of process is mostly based on the user’s carelessness. The same process of getting virus into your computer on network as virus can move through that process.

5.         Clicking Unknown Links

This is another internet form of infecting your computer with virus. Links are found almost in every platform on the internet ranging from websites, social media, and online advertisements.

As I stated earlier, virus do come as camouflage, you do not have to expect a virus to come clean to display its true self.

To keep your computer safe from virus emanating from these links, it is much better not to click on any of these links. The common tactic being used is to create a link to look like a legit link but when you click on it redirects the user to another page not intended.

At times, a computer user may mistakenly click on this kind of link. When this situation occurs, cancel the operation that might come afterwards.

If you have an effective Antivirus software installed on your computer, it will take care of any virus invasion that must have taken place within that short period.

6.         Checking Out a Website

You be careful when checking a website, as that website may be owned by an unscrupulous person whose agenda is to cause havoc. A malicious website while surfing the web, will enable virus constructed with that website to install itself on your computer.

Some malicious website may at times, while checking them out transfer corrupt files to you and even have access to your computer files. Online advertisements in websites with malicious code embedded in them, will definitely cause virus invasion if those advertisements links are clicked on, to direct you to that malicious website.

7.         Not Installing a Trusted Antivirus Software

Having antivirus software installed on your computer pays a lot and will do a great job in keeping your computer safe from any virus attack.

Trusted antivirus software can remove any existing viruses on your computer and prevent further attacks in future during operation on your computer.

The reason why I stated ‘trusted’ is because a virus can be designed in form of an antivirus while may be calamitous for your computer. If you have a trusted antivirus installed, always get an updated version of it.

8.         Some Malware Just Find their Way In

Virus could be on your computer and you might not be aware of it. The creators have even find ways for virus to make way into your computer without engaging in any dangerous activity on your computer.

Most times, it is when it becomes too late that users will realise the virus invasion.

9.         User’s Faults

Most causes of virus invasion on many computers boils down to the user faults. Most users do not follow instructions when the need arises and at times some are just adamant while being aware of risks present in engaging in computer activities that may expose their computers to virus attack.

On the other hand, some computer users are not informed about basic guidelines in keeping computers safe from virus and all other malware attack.
