How to Know If a Computer Virus Sneaked in Your Device
Written by ellawatson

When there’s a computer, there is definitely a source of its sickness.

Come on! Why don’t we just accept the fact that machines do get sick and that they need our help!

The first assistance you can offer a device like your PC or laptop is being careful with the virus.

Computer viruses aren’t something new in 2021.  There have been numerous studies and researches about them. They have hacked or damaged or destroyed and literally wasted hundreds and thousands from their owners’ pockets.

It has been for them only you get to buy specially designed apps known as the Antivirus. It has been for them those pages after pages of content and guidelines were produced on how to deal with a virus in your computer.

Like this one!

A lot has been done since the first computer virus kicked in, right?

Now companies around the world are working with special Malware protective measures to ensure robust security to their enterprises and their data.

So, it is time you should know what these computer viruses are and if they are hiding somewhere in your device.

  • What Is a Computer Virus and How to Know If You’ve Got One in Your Device

To put it simply, computer viruses are just like their biological counterpart.

A flu virus makes you work in a lethargic way. It makes you sneeze and cough or probably puke at times. It doesn’t make you concentrate on something productively, and your body suddenly demands more rest than it needs.

Similarly, a computer virus attacks the operating system or some targeted software in your device. It makes it run slower as it lags.

The device can respond erratically, like hanging, crashing, shutting down, or restarting without your instructions. It attacks the hard drive or the disk space of a device and takes control of the system files.

Your valuable data can be deleted or misused with a virus. You may lose control over your system.  Your device may get damaged in the internal hardware due to such misuse.

And all of that means expenses. You really don’t need to bear the rising and, sometimes, the sky-high costs of fixing a computer. Instead, it is better if you invest at first in using an Antivirus, even if that requires you looking for a small loan in Ireland online.

Prevention is truly better than cure.

But, how should we prevent ourselves from computer viruses?

By reading about the following symptoms of computer virus infection:

  • Annoying ads, messages and pop-ups?
  • Your computer crashes
  • Internet traffic increases and that too suddenly
  • Your default security setup is disabled
  • Your colleagues or others get strange messages from you
  • Limited access to control panel
  • Icons on your desktop that don’t make sense
  • Browser page interface changed without your involvement

Let’s know what these viruses actually do with our systems.

1. Annoying Ads; Messages and Pop-ups?

You turn your computer on and start typing a mail on a fine, bright morning with lots of happiness in your mind, and suddenly a pop-up appeared on your screen asking you to book some sort of appointment you didn’t expect.

Probably you got a mail asking the same or something different.

Or too many advertisements relating to the product you didn’t know or want!

These disguised programs mimic a legitimate web browser program. It is supposed to collect your browser data, history and essential codes or passwords you use while surfing the net.

Since they steal data being hidden in this way, they are known as Spywares.

Prevention: You need an antivirus. But, you should not also click on or investigate those messages. That’s going to be the first wrong thing you don’t want to do.

2. Your Computer Crashes

Your computer may crash and show the Blue Screen of Death (BSOD as they call it), informing you that there has been a critical system error and that the computer has recovered itself.

While uninstalling other programs may also create this problem (as they leave something called the registry keys responsible for crashing your computer), it can be most likely for malware to crash your computer.

Have a detailed analysis of the computer and find out if you have installed any program or not in recent times. However, in cases like these, don’t hesitate to go for antivirus and install one as soon as you can.

3. Internet Traffic Increases and That too Suddenly

Now, most computer viruses affect your computer through the Internet.

If your Internet activity increases where you need to visit many sites (and many kinds of them) to involve yourself with a diverse workforce, then it is likely your device will get infected.

In case that happens, then you need to do some background check of your computer.

Find out if you have any app running in the background. Check if all the updates for your OS have been downloaded.

If that problem still persists to happen, then it can be caused by malware.

Invest in antivirus and fix this issue ASAP. If needed, don’t think twice before looking for a small loan in Ireland because these personal loans are unsecured. You can repay them off with the money you earn and you really do not need to consider an asset for collateral.

4. Your Default Security Setup is Disabled

Each and every computer comes with a built-in antivirus system.

But, they may not be enough to tackle an advanced or adaptable antivirus.

When your PC is in trouble and that it stops working the way you want it to, you go ahead and troubleshoot it.

Probably you reboot it and delete a number of files or apps that you deem suspicious.

But that’s not going to be enough in case there’s malware involved.

Take care of the problem with antivirus and make sure you are doing it fast.

5. Your Colleagues or Known Ones Receive Strange Messages from You

Similar to a biological virus, a computer virus is designed to SPREAD.

By using messaging or mailing on your computer, a virus wants to spread itself in the devices of others in order to hack their systems and steal their data.

Once your colleagues, buddies, or family members receive strange messages, you can be aware of a virus.

These viruses use coded words or URLs in messages.

Ask who received them to ignore or delete those messages. Check your browser history and reinforce your online signup by changing passwords and running background checks.

You can also use two-factor authentication systems.

6. Limited Access to Control Panel

When your control panel is disabled or is denied access, then you can be sure that a threat probably exists in your computer.

You may try out opening your control panel in the safe mode to see if that works.

Two situations might be involved.

One, your computer has been infected by a computer virus.

Two, it might have been attacked by what professionals call a ‘cyber-attack.

It is better to run a complete scan using your antivirus app and then talk to an IT professional if the former step fails to help you gain access to the control panel.

7. Icons on Your Desktop that Don’t Make Sense

They call it the PUPs.

And that stands for Potentially Unwanted Programs, which are piggybacked by your computer virus in case you mistakenly downloaded them.

These software will get installed on your device without your instruction and will appear on your desktop. They can potentially harm the OS and other files (even hardware). They also have the power to back up the primary virus that brought them in.

Try to uninstall them or remove them using your antivirus product.

8. Browser Page Interface Changed without Your Involvement

So, you have finally decided to go for a better antivirus product or probably a new one with the help of a small online loan in Ireland and clicked on your favourite browser.

And you found out that the page interface is completely changed.

Often, you will be redirected to a malicious website that will keep showing you pop-ups THAT WOUDN’T JUST GO AWAY EVEN IF YOU CLICK TO CANCEL THEM.

Suspicious, right?

Well, it is definitely the work of a computer virus.

You might have encountered this issue in your Smartphone as well.

Try to scan the browser with your existing antivirus software.

If possible, remove it and reinstall it.

Always try to avoid the link in which the virus is redirecting you. It does so in order to download more malware to your device to extend its malicious mission.

  • To Conclude

Well, the war between these computer viruses and antivirus will continue.

We’ll be witnesses to that…all of us.

But, we must always keep our data and our privacy safe from these potential threats.

To do that, just be a good buddy to your antivirus product and provide it with checks and updates.

Your computer will run as good as a new one.
