Most Common Types of Malware That You Should Know

Malware, a short form for malicious software, is any software that is intended to harm or exploit computer systems. It can take place in a variety of ways, including viruses, worms, Trojans, ransomware, adware, spyware, and scareware.

Malware is capable of stealing sensitive data, disrupting or damaging computer systems, and gaining unauthorized access to computer networks.

There are many types of malware, and new types are constantly being developed. Here are some common types of malware that you should be aware of:


A virus is a type of malware that can replicate itself and spread to other computers. It usually requires a host program or file to function and is often attached to legitimate programs or files as a way to spread.


A worm is a type of malware that can replicate itself and spread to other computers without requiring a host program or file. It is often spread through email attachments or through vulnerabilities in software or operating systems.


A Trojan is a type of malware that disguises itself as a legitimate program or file and tricks the user into installing it. Once installed, it can perform a variety of malicious activities, such as stealing sensitive information or deleting files.


Ransomware is a type of malware that encrypts a victim’s files, making them inaccessible until the victim pays a ransom to the attacker to decrypt them.


Adware is a type of malware that displays unwanted advertisements on a computer. It is often bundled with other software and can be difficult to remove.


Spyware is a type of malware that tracks a user’s online activities and collects sensitive information without the user’s knowledge or consent. It can be used for a variety of purposes, such as tracking browsing habits or stealing login credentials.


This is a type of malware that employs scare tactics to persuade you to perform a specific action.

Scareware most commonly uses an operating system style window that appears on your screen and warns you that your system is in danger and that you must execute a specific program to restore normal operation.

If you agree to execute the specific program, your system can be infected with some kind of malware.

How Malware can Spread?

Malware can be propagated via infected email attachments, malicious internet downloads, infected E-mail messages or instant messages, vulnerabilities in software or operating systems, or plugging in infected hardware like a USB.

Malware can be difficult to detect and remove, so it is critical to use antivirus software and maintain safe browsing habits to limit the chance of infection.
