Guide: 4 Types of Common Malware Explained – Updated 2021

Have you ever realised that there are various kinds of malware? Below are four types of common malware you may want to be aware of:


Ransomware is a little PC infection that scrambles all the documents on a tainted computer or laptop. Once encoded, the PC becomes unusable on the grounds that none of the information put on it is easily accessed.

On the off chance that your PC is infected by ransomware, you will see a message on-screen offering to deliver the encryption key that will open your documents. The catch is that you need to pay a Bitcoin ransom expense to get the key hence its name origination.

Paying demands isn’t normally a smart thought as there is no assurance that the programmer will deliver the decoding key. Rather you should guarantee you generally have a current reinforcement of your documents. Reestablishing your own information is substantially more solid and more secure than conforming to cybercriminals.


Trojans, named after the Greek legend of the Trojan Horse, are a type of malware that sneaks onto an unsuspecting victim’s computer or laptop. Once introduced, the trojan does basically nothing until it is actuated.

Much the same as the soldiers covered up in the wooden pony box at the back of the greek horse, a trojan sneaks behind your safeguards and afterwards dispatches an assault from within.

This type of malware may erase or harm information, or basically go about as an entryway, permitting programmers to access and utilise the contaminated PC whenever they feel.

Trojans are a great way to connect a PC or Laptop to a botnet, this helps to launch Distributed Denial of Service attacks (DDoS) not only this they are also used to steal information directly from unsuspecting users.
