Computers are quite prone to viruses. A poor security system and lack of anti-virus programs can often lead to a virus infecting your computer. Therefore, checking to see if your computer has a virus regularly is always advised.  

Key Takeaways

Why Having A Virus On A Computer Is Dangerous?

Viruses are so dangerous because they put all your personal and private information at risk. Viruses allow hackers to access your computer by creating backdoors and open ports. Once the hackers gain access, all your personal data is exposed to them.

This means any bank details, passwords, credit/debit card info, social security numbers, and so on are all available to them. Hackers can easily use any of these details for their benefit. They can easily carry out any activity they like using your resources.

Your computer may be used to carry out suspicious activities without your permission or knowledge. You can be a victim of identity theft, fraud, or similar activities.

What Types Of Viruses Can Take Over Your Computer?

A virus may cause the same harm to your files and data, but it is still divided into certain types. The division primarily concerns the place it resides and spreads from. Mentioned below are the most common types of viruses.

  1. Network Virus: This virus takes over the device when connected to a suspicious network. Any other devices connected to the same network are at risk of catching the virus.
  2. File Infector Virus:  This virus initially resides in executable files (.exe files). The virus does its damage once you try to run the file it is residing in. Eventually, the virus proceeds further to cause damage to your other files and applications.
  3. Boot Sector Virus: This virus initially resides in your computer’s hard drive. The hiding spot of the virus is the boot sector. Therefore, as soon as you boot your computer, the virus spreads. Any other devices connected to your computer are at risk of catching the same virus.
  4. Macro Virus: This virus hides in files. The files mainly comprise Ms. Word, Excel, and PowerPoint files. The virus spreads on your computer when you open these infected files.
  5. Resident Virus: This virus may initially reside elsewhere. However, it may spread from the initially infected file or application to your memory. Hence, the virus may still be on your computer even after you remove the infected file or application.

How To Tell That Your Computer Has A Virus?

A virus is not something you can get a hold of right away. It hides in your computer; therefore, it takes work to catch it. However, for the sake of your ease, we have provided the most common symptoms that indicate the presence of a virus on your computer.

Long Processing Time

In case of a virus presence on your computer, you will notice your computer taking much more time processing small tasks than usual. Your files and applications will take a considerably long time to load. This may indicate that there is a virus on your computer.

Unknown Websites Connections

You will notice your computer trying to load up websites you did not search for. This is a huge indication of a virus presence on your computer. That is because your computer never carries out such functions itself. You have to carry out such tasks; they do not happen automatically.

Sudden Pop-ups And Images

Explicit ads or images and website pop-ups may appear when surfing the internet. If you notice this happening more than usual, a virus may be hiding in your computer.

Strange Errors And Programs

You may run into unusual and unexpected errors when trying to run an application on your computer. Not only that, but you may notice the same applications behaving differently than they are supposed to. Moreover, you may encounter programs you have never seen on your computer.

Unusual Social Interaction

Once activated, the virus can spread to other devices by sending infected links to other people through your social apps. For instance, if you notice an email sent (Not by you) through your account to people with a link, it may be a virus-infected link.

Failure In Downloading Anti-Virus Application

At times, viruses are programmed in a way that they can defend themselves. The anti-virus application does not work in their favor. Therefore, they might prevent your computer from being able to install such applications.

Missing Files

Another indication of a virus on your computer is missing files. You might notice your files missing, misplaced, and even with their icon changed. Again, your computer does not carry out such tasks itself. Therefore, this can be a doing of a virus.

Space Shortage

As mentioned above, a specific virus type hides in your hard drive. Viruses take up much space; therefore, if you notice a sudden shortage on your hard drive, it may be because a virus is hiding there.
