Guide: 8 Types Of Computer Virus Plus How To Remove Them – Updated 2022

One day, you’re using your computer with no issues. Suddenly, strange effects start occurring. Nothing is working appropriately, and your computer seems to have grown a mind of its own. You sink as you assume that you’ve got a computer virus.

It happens to the most careful of us, including governments. Computer viruses are incredibly stressful, particularly when all of our lives are so dependent on using computers.

When dealing with a computer virus, it’s essential to understand what you’re up against, including all the different types of computer infections that you could be facing.

Below I will go into detail of 8 common types of Viruses and then explain how best to remove them:

Types of Computer viruses.

All computer viruses are diverse. They affect different regions of the computer in order to gain from different results. But what’s a computer virus?

Put simply, a computer virus is a malicious piece of code that can circulate from host to host, infecting every computer along the way.

They’re designed to change the way that your computer works. Once a virus has gripped aboard, it can damage the system, leading to the theft, decomposition, or destruction of data.

Once you’ve got a virus, you’ll need to take some course of action to clear your computer of it. But first, let’s take a better look at some of the most common types of computer viruses.

1. Resident Virus.

A resident virus is a type of computer virus that stores itself in the computer memory. From there, it can dissolve and alter your system operations. These contagions are one of the worst to get, as they’ve near-complete control over what they can penetrate.

They can more worryingly attach themselves to any antivirus software you have and start attacking that. We deal with this a lot with our remote virus removal service.

2. Direct Action Virus

Occasionally known as a file infector virus, these viruses work by attaching themselves to. EXE or .COM files.

Once the files have been implemented or installed. They can use this original file to pierce the other folders and files on your computer and start spreading. 

Direct action viruses can hamper your capability to access files. Still, if you have a good degree of computer virus protection, then your antivirus software should be suitable to get free of these effortlessly.

3. Multipartite Virus.

Most viruses work by honing in on either executable programs or the boot system. The multipartite does both. Think of this virus as commanding numerous ‘tentacles.’ They can affect nearly every part of the computer by targetting network operations, programs, or folders.

They can be gruelling to get clear of without sophisticated antivirus software.

4. Macro Virus.

Macro viruses thrive in programs like Word and Excel. This is because Word and Excel is written in macro language, which the virus attempts to mimic to gain access to your folders and files.

They’re extremely deceptive, as what can appear like a simple Word document but, when you click on the document, your computer or laptop will either be infected right from the get go. 

Or in some cases you’ll be diverted to a vicious website to further infect your network/machine.

Also, these computer viruses could frequently dispatch themselves out to others through your contact list, If that wasn’t enough. Hence, It’s very important to get a macro virus sorted straight away.

5. Browser Hijacker.

The browser hijacker remains the least dangerous virus on this list, but it can still be an annoyance.

Browser hijackers work by removing the former home screen on your browser and replacing it with a new one, it does this unrelentingly to show you adverts.

6. Polymorphic Virus.

How do you catch an entity that keeps morphing? That’s the problem with polymorphic viruses.

Most viruses possess a set law or carry a bunch of set rules, and once your antivirus software can figure out and determine that law or set of rules it exists by, it can destroy the virus. 

Polymorphic viruses, nevertheless, have a set of rules that’s constantly changing, making them incredibly hard to hunt down and annihilate completely.

7. Boot Sector Virus.

Boot sector viruses used to be really common in the days of the floppy disks. They’re not so common now, but they do still live.

Boot sector or boot time viruses hang out as a file on a USB drive, external hard drive, the cloud or indeed an email attachment. 

Once actuated, they latch on to the computer’s boot record and harm the system before the operating system thinks about turning on or even worse before your antivirus boots.

8. Web Scripting Virus.

Web scripting viruses can be genuinely stressful to deal with.

They work by sneaking past your web browser’s security. This can allow hackers or any other immoral person with the proper knowledge to expose your data. 

This can lead to details of your personal or financial ID slipping into the wrong hands.

What to Do About Computer Viruses.

That list can look scary, and virus removal can feel daunting, but there are lots of stuff you can do to fight against computer viruses.

The first thing to know is that early action is always easier than response. Having a firewall and some antivirus software is an excellent place to start. 

However, don’t feel too comfortable with antivirus alone, as I have spoken about before here, your antivirus will have a list of “Known” viruses. 

What about the ones yet to be known or those that your antivirus software research team do not even have the money to research. 

For example, I am sure a larger company like Microsoft would spend a fair amount on antivirus research, yet windows still is susceptible to get infected. 

Also, take some time to understand about viruses. When you know where and when you’re likely to come across one, you can take the action required to avoid infection in the first place.

Of course, occasionally you just get caught out. However, go ahead and boot up your antivirus software and run a scan, If you’ve picked up a virus that can be easily dealt with at home. 

The software will examine the entire system for signs of a virus and also annihilate any that it’s able to remove. I wrote about some good free antivirus software here also if you need one.

Occasionally this isn’t possible. In this case, you’ll need to take your computer to an expert to get it assessed, If you feel you’ve got a more rigorous virus that you can’t get clear of yourself. 

For example, I have the know-how and proficiency to track down indeed the most evasive viruses due to the 16 plus years of experience in doing so, both here and also on our data centres at Top Level Traffic.
