Computer viruses are the well-known bad boys of malware who have been around since the dawn of computing. These malware programs are designed to regenerate and spread from one device or system to another like a digital wildfire.

When you carry out an infected program, this little digital parasite attaches itself to your computer’s files and programs and quickly spreads throughout your digital system. Stuxnet one of the most sophisticated computer viruses ever discovered in 2010 caused physical damage by disrupting the operation of centrifuges, highlighting the potential for cyber-physical attacks.

They are cunning, intrusive and capable of a wide range of negative consequences, including data corruption or loss and system breakdowns. By implementation of antivirus software, you can keep your system safe and secure against these annoying digital pests. 



A Trojan or Trojan horses are not just ancient war machines – they are also a type of malware that can sneak their way into your system by disguising themselves as legitimate software or files. They are like digital chameleons, blending in with their surroundings to deceive unsuspecting users into executing them.

Trojans may not replicate themselves like viruses, but they are just as dangerous. Emotet a banking Trojan allows cybercriminals to carry out fraudulent activities, giving access and control computers remotely, stealing sensitive information and spying on online activity. 

Trojans can conduct a variety of destructive tasks once they have gained access to a system, including opening up backdoors for remote access and assisting in the infection of additional malware kinds. You can help prevent Trojan infections and keep your system safe and secure by exercising caution when downloading files and by using reliable protection software.



Spyware is like a digital stalker that secretly gathers information about your online activity without your consent. You will feel like someone is constantly watching your every move online which can be a distressing experience.

FinFisher – Spyware tracks your keystrokes, captures screenshots and even steals your personal information – like a digital thief lurking in the shadows of your computer. They install additional software and change the settings on your device, leaving you vulnerable to even more digital threats. 

Spyware can sneak its way into your system through various channels, such as malicious downloads, email attachments, or compromised websites. But do not let spyware catch you off guard. Use anti-spyware software and practice safe browsing habits, to prevent spyware infections and keep your online activity private and secure. 



Worms are like a digital version of the common cold – they spread quickly and infect systems before you even know it is happening. Mydoom represents an example of Worms that are unlike viruses. They self-replicate and spread rapidly across networks, exploiting software vulnerabilities in digital systems without any user interaction required. 

Worms consume network bandwidth, overload servers, and compromise system performance. They cause a digital traffic jam that brings your system to a grinding halt. Consistently applying security patches and maintaining robust network defences are crucial in defending against worm attacks and keeping your system sheltered.



Ransomware is a digital nightmare that leaves you feeling powerless and vulnerable. This type of malware encrypts your files or locks you out of your own system, demanding payment in exchange for the return of your data. It has become a significant threat in recent years, targeting both individuals and organisations.

WannaCry serves as an illustration of ransomware holding your data hostage and demanding a ransom, typically payable in Bitcoin to cybercriminals, costing a few hundred to thousands of dollars. Its attacks can cause significant financial losses and operational disruptions and compromise the privacy of sensitive data. 

Do not let ransomware attacks get the best of you. With proper knowledge, threats intelligence and robust security measures in place, you can protect your data from these digital bandits. 


Mobile Malware 

When you scroll through your favourite app and suddenly your device starts acting strange. You try to unlock it, but you are locked out, and your data is compromised. That is how mobile malware invades your smartphone or tablet, leading to grave consequences like data theft, privacy breaches, and financial losses. 

Triada is a highly insidious rooting Trojan that emerged as a significant Mobile Malware threat by infiltrating the supply chain and infecting millions of Android devices with pre-installed malware. If you suspect that your mobile device has been infected with malware, take swift action by running a malware scan using reputable mobile security software, which can detect and remove malware from your device.  



Keyloggers like digital spies silently record every keystroke you make, stealing sensitive information like usernames, passwords and credit card details. They are malicious programs that record keystrokes on infected systems. Keyloggers can be introduced to a system through various means, such as through phishing emails that trick users into clicking on malicious links or downloading infected attachments.  

The Olympic Vision keylogger represents a notable example of this intrusive malware. Hardware-based keyloggers can capture keystrokes even if the computer is not connected to the internet and are difficult to detect. Keyloggers pose a significant threat to user privacy and security and enabling a robust firewall on your devices will function as a barrier against keyloggers preventing any losses.



Adware, short for advertising-supported software, is like a digital billboard that pops up on your screen without permission, disrupting your browsing experience and potentially compromising your privacy. Adware can redirect search results, sell your personal data to advertisers without your consent and even lead to unintended downloads of additional malware. 

The Fireball adware is a prime example of how intrusive and pervasive this malware can be, infecting millions of computers worldwide. While adware may seem less harmful than other types of malware, it can still impact system performance and invade your privacy. To protect against adware, it is crucial to utilise ad-blocking tools and keep your operating system and application updated.



Rootkits are like a passkey that grants hackers unauthorised access to your computer system, providing them with elevated privileges and enabling surreptitious activities.

One notorious rootkit, Zacinlo, is a prime example of the damage that these sneaky digital invaders can cause. It allows cybercriminals to control victims’ devices discreetly, evading detection and escalating potential damage to the system. 

Combat rootkits effectively through the employment of robust security measures. Intrusion detection systems can help identify potential attacks and raise alarms when suspicious activities occur. 


Fileless Malware 

Fileless malware acts as a digital ghost that haunts your electronic system, leaving no trace behind. It is a type of malware that represents a stealthy and evasive breed of malicious software, making detection and eradication significantly challenging. Unlike traditional malware that resides in files, fileless malware manipulates native operating system components, making it difficult to detect and remove.  

The Astaroth malware serves as a prominent example of fileless malware’s dangerous capabilities. Fileless malware can evade traditional antivirus and anti-malware software, leaving your system vulnerable to attack. You can prevent this malware spread by implementing behaviour-based analysis and intrusion detection systems, regularly updating operating systems and applications, and using endpoint security solutions that can detect and block suspicious activity in real time. 



Bots are like digital minions that can perform repetitive tasks without human intervention. However, when used maliciously, bots can become powerful weapons in the hands of cybercriminals. These nefarious bots allow attackers to launch massive floods of attacks, overwhelming systems and compromising security. Bots’ malware can be difficult to detect and remove, making it a significant threat to networked systems.

The Echobot botnet is a prime example of their destructive potential – like a swarm of digital bees that can launch a variety of attacks such as DDoS attacks, credential stuffing and malware distribution. Protecting against bot malware requires a multi-pronged approach that involves several layers of defence, a combination of network security, user education and regular system scans. 


Wiper Malware 

Wiper malware is a digital wrecking ball that aims to permanently destroy or erase data by corrupting the system. Unlike ransomware, which holds data hostage for ransom, wiper malware is all about causing irreversible damage or disruption. Threat actors often use this destructive malware to cover their tracks after exfiltrating information from a network or to cause chaos and confusion. 

WhisperGate is a prime example of the devastating consequences of wiper malware attacks. This destructive malware is like a digital hurricane that can sweep through your system, wiping out all your data and leaving you with nothing.  

Proactive defence, regular updates, and a multi-layered security approach are essential in protecting your systems and mitigating the potential impact of these destructive threats.


Cryptomining Malware  

Malware known as “crypto mining malware” uses a computer’s computing power to mine cryptocurrencies. Malware that does crypto mining can seriously affect a system by consuming more energy, slowing it down, and overheating hardware.

This malware runs in the background and begins to use the computer’s processing power to solve complex mathematical problems that generate digital currencies, such as Bitcoin or Monero. PowerGhost is one example that utilises the computing power of infected systems to mine cryptocurrencies. It can also compromise the security of the system by facilitating other types of attacks and stealing sensitive data.

PowerGhost is an instance of such malware operating silently in the background, utilising the processing power of compromised computers to solve intricate mathematical problems that generate digital currencies like Bitcoin or Monero. Additionally, it poses a risk to system security by enabling other forms of attacks and potentially exfiltrating sensitive data.

By using browser extensions that block cryptocurrency-mining scripts, you can significantly reduce the risk of your system being infected with crypto-mining malware. 


Logic Bombs 

Logic bombs are a potent threat that can be challenging to detect since they can remain hidden on a system for an extended period. They can be created and inserted into software by malicious insiders, such as disgruntled employees or contractors, or by external attackers who have gained unauthorised access to a system. 

Logic Bombs are malicious code that lies dormant on a system until a specific trigger condition is met. This trigger could be a certain date and time, the termination of an employee, or any other event that the attacker has programmed the bomb to recognise. Preventing logic bomb malware requires access controls, regular security audits, intrusion detection and prevention systems, anti-malware software and security awareness training. 


Polymorphic Malware 

Polymorphic malware is a type of malware that constantly changes its identifiable features to evade detection by security solutions like antivirus software. Storm Worm a type of polymorphic malware uses advanced techniques that involve frequent mutations to its code structure, making it unrecognisable to many detection techniques that rely on pattern-matching or signature-based detection methods. By doing so, the malware becomes unrecognisable to many detection techniques that rely on pattern-matching or signature-based detection methods. 

Use advanced security measures like behaviour-based detection, sandboxing, and threat intelligence to detect and isolate polymorphic malware. These techniques can identify and isolate the malware, even if it has changed its appearance and structure, reducing the risk of damage and data loss. 


Hybrid Malware 

Hybrid malware, also known as combo malware, is malicious software designed by blending different attack techniques to execute complex and multifaceted attacks. This type of malware includes traits from various malware families, including Trojans, worms, viruses, adware, or spyware, to create a single, packaged attack. 

Gozi is a hybrid malware that combines the features of a banking Trojan with rootkit functionality, resulting in a potent “banking Trojan on steroids.” This combination enables Gozi to achieve extensive access and control over compromised systems, going beyond typical banking Trojans.

In contrast to other kinds of malware, hybrid malware uses crossbreeding propagation strategies to carry out a number of tasks in a single, destructive operation. Once it has gained access to a system, it can bypass its security, install malicious code and carry out numerous damaging operations simultaneously.



A backdoor is a software created to give a covert mechanism for hackers to break our cybersecurity defences and acquire high-level access to our digital domains, much like a backdoor in a physical building permits burglars to enter undetected. They are typically categorised as a Trojan, which frequently enables them to go unnoticed for long stretches of time, making them very hazardous.

Backdoor viruses can give internet criminals access to your computer and then allow them to carry out a variety of harmful tasks including installing further malicious software on your computer or stealing sensitive data.

Backdoor malware can be defended against by implementing a multifaceted cybersecurity approach that uses firewalls to block unauthorised access, network traffic monitoring to look for indications of unusual activity, trusted anti-malware solutions installed and routine software updates.



Scareware is a malicious tactic employed by scammers to manipulate and deceive unsuspecting computer users. It preys on people’s fears and attempts to trick them into downloading or purchasing software that is either useless or altered with malware. In certain circumstances, scareware may serve as a precursor to ransomware attacks; on the other hand, it is designed to bombard users with pop-up alerts without imposing actual damage to their files.

Vigilance and adherence to secure computing practices are essential to protect oneself from scareware and other cyber threats. By remaining aware of potential risks, questioning suspicious messages or alerts and following best practices for secure computing, you can significantly reduce the risk of falling victim to these malicious tactics.


How to detect malware attack 

Identifying a cyber intrusion can be a daunting task, as malware is crafted to operate stealthily, avoiding detection by security systems. Nevertheless, there are certain indicators that can assist in recognising a potential cyber-attack.

  • Malware infection can cause your computer’s performance to slow down, making it difficult for programs to load and run.
