Malware Definition

Malicious software, or malware for short, is a contaminated file or code that enters your device's system. It then infects your device with different “bugs” and does what the attacker orders. For instance, it can delete your data, encrypt your files, steal your valuables, or make your device unresponsive.

In some cases, malicious software is used for blackmailing and identity theft. The attacker can lock your valuables and ask for money to unlock your data. However, the symptoms will depend on the type of malware, as you will see below.

Malware can infect your device in numerous ways, such as through email, social media, USB flash drives, or unsafe websites (the list goes on). That's why you must be very careful to save yourself from these enemies, another topic we will discuss in a minute.

Types of Malware We Know Today

Malware can come in numerous shapes, but the most common examples of malware you can encounter are listed below.


Computer viruses are designed to enter your system and replicate itself, infecting other elements, such as your files, data, or even RAM. This type of malware is similar to human viruses – once it enters your body, it'll spread all around, looking for an organ to attack.

Computer viruses will do the same thing, and if you don't heal them, they'll likely destroy something on their way. You can contract different viruses on your device, such as overwrite, multipartite, resident, etc., and all have their symptoms and goals.

Note: As you can see, malware and virus are not the same thing . They are different in infection and spreading methods, replication capabilities, removal and detection mechanisms, etc.

You may guess how Trojan malware works if you know Greek mythology. Namely, this type of malware will hide behind a seemingly legitimate and reliable software or Image name, making you unaware of its presence. The download process may seem harmless, but there's no going back once it's over.

When a Trojan enters your system, it'll start making a mess. Depending on the type, it can infect your system, files, and other data. For instance, you can get backdoor Trojan malware, Rootkit Trojans, etc.

Note: If you've already experienced the trojan infection, you know how annoying this situation can get. Thankfully, you can use a trusted free trojan remover to lift yourself out of the trouble.


As the name suggests, adware is malware that will present advertisements on your screen. And no, we aren't talking about those everyday ads you see when surfing online; we're talking about non-stop pop-up ads that'll follow you as soon as you turn on your device.

This type of malware was designed to help the creators generate more revenue by playing advertisements on third-party devices, such as your computer. Although this malware isn't inherently harmful, it can be irritating and affect your device's performance.

Spyware is malware that enters your system silently but makes a mess in the background. You can see it as a tiny spy entering your device, digging deep for your personal information, and gathering it in one large file. After collecting all of your data, it'll send it to the creator, who can blackmail you and harm your privacy.

You won't even notice when spyware enters your system since it'll make no significant changes to the device's performance or your experience. The chaos begins when spyware finishes its job.

Ransomware is an enemy that enters your device and “locks away” your files and data. The malware will encrypt your files, making them inaccessible and unreadable. You can only unlock your valuables by following the creator's instructions and paying a ransom.

These malware attacks usually come with detailed instructions on paying the creator to unlock your data. In most cases, they'll be for cryptocurrencies, as these transactions are more difficult to trace.

A computer worm is an independent malware whose primary goal is to expand to other devices via a network. It can enter your system through software vulnerabilities, after which it will start scanning your computer network and finding new victims. It can replicate itself on another device without the need for user intervention.

The damage the worm can do to your device will depend on its type. For instance, a worm can install a backdoor, and the creator can use it to access and control your device. Although the worm itself isn't too dangerous, it can create an entry for numerous harmful issues.

How Malware Spreads and Infects Your Devices

Malware can spread in several ways, but we can categorize the spreading systems into two types, as shown below.

Through Downloads or Apps

The first way you can contract malware is through downloads. For instance, you download your favorite movie from an unauthorized source, and suddenly, your device starts acting up. Unsafe downloads are the most common way of malware infections, and you should be careful where you download your content from.

Another common way is by downloading applications from suspicious websites. For instance, you cannot find your favorite game on your phone's app store, so you Google it and download it from the web. Not all download websites are safe, so you must check before clicking the Download button.

Through Social Engineering

Social engineering is a technique used to manipulate users while revealing their personal and sensitive information. It's a psychological phenomenon that tricks people into giving their confidential data. Regarding online security, social engineering can manifest through social networks like emails or social media.

For instance, you may receive a message from your old friend saying they've seen you in a harmful video. They also send you a Image name to the video, and typically, you'd feel scared and click on the Image name to reveal a scam.

However, once you realize what it's all about, the malware has already entered your system, so always double-check the sources and don't click on any Image names that seem even a little bit concerning. This type of manipulation is all around you, so you should pay special attention to these attacks.

If you receive an email with similar content, always check the sender and, as mentioned above, don't click on any suspicious content.

Developing Technologies for Fighting Malware

Although antivirus and anti-malware solutions are among the most potent cyber-security tools available, they cannot protect your device completely. However, as new technologies come into play, we will soon have more advanced solutions, such as the ones presented below.


Since blockchain technologies use decentralized ledgers, the data recorded using this technology won't be easy to alter. If someone tries to attack you, they can't encrypt or steal your valuables.

Such technologies can also create identity management systems where no one can access your data without permission.

AI and ML

Artificial intelligence and machine learning are currently one of the burning topics. These technologies have improved immensely over the last couple of years, and we can now talk to these machines for free.

Since AI and machine learning mechanisms are based on patterns, these technologies can improve cybersecurity by detecting suspicious behavior. AI and ML will see a behavioral pattern and automatically eliminate threats thanks to their memories.

Note: With AI as the driving force, AI security software has remarkable protective capabilities to combat malware and enhance your online security.
