What Is Malware
What is Malware? Malware is software designed to damage computers and computer systems. It is used to bypass access control to damage computer functions, and steal data. In short, malware is a piece of software designed to damage computers, tablets, phones, computer systems, networks.
Malware can cause damage and destruction to your organization. Some people may ask “what are the 4 types of malware” or “what are 5 types of malware”. Actually, there are many types of malware and they are increasing every day. Now, let’s see some common types of malware.
The 9 Common Types of Malware

Types of Malware
The virus is one of the most common types of malware. The virus is designed to destroy its target computer by destroying data, reformatting the hard drive, or completely shutting down the system. They can also be used to steal information, create botnets, steal money, provide advertisements, destroy computers and networks, etc.
When you run infected programs, viruses can attach themselves to programs and execute code to copy themselves and spread to other computers. Computer viruses require human intervention to spread to other computers and are usually spread via email attachments and Internet downloads.
Virus is undeniably the leading threat to computer security, so I think it is necessary to give a brief introduction to the common types of computer virus.
Worms are the most common type of malware, which uses operating system vulnerabilities to spread in computer networks. The worm can be more destructive than other types of malware since it is a standalone program that can copy itself to infect other computers.
They can quickly infect a large number of computers, consume bandwidth, and overload the webserver. They can also encrypt data for ransomware attacks, steal information, delete files, and create botnets.
Have you ever noticed an ad suddenly appeared on your computer? This may be adware. Adware is a type of malware that causes ads to be displayed on your computer and it can generate revenue for ad creators.
It is usually displayed in the form of pop-up advertisements or advertisements embedded in software or programs. Adware can also provide spyware and is usually easily hacked. To know if you have been hacked, this post - How to Know and What to Do If You Have Been Hacked is what you need.
How to remove adware from Windows 10? After reading this post, you know some things you should do. Just follow the guide for adware removal.
Spyware is installed on your computer without your permission and is designed to track your browsing habits and Internet activity. When hackers use spyware, they can access any type of sensitive information of yours.
Spyware can be spread by exploiting software vulnerabilities, bundling with legitimate software or Trojan horses. It is commonly used for identity theft and credit card fraud. Although spyware is dangerous, fortunately, it is easy to remove.
Malvertising is not the same as adware. Legitimate advertisements will be attacked by malware through malvertising, and then the malware will be sent to the target computer. Cybercriminals may place ads on legitimate websites. When you click the ad, the code in the ad will redirect you to a malicious website or install malware on your computer.
Ransomware is a type of malware that can capture your data and demand payment to release it back to you. It encrypts files on the hard drive or locks the system and displays messages. It aims to force you to pay the attacker to release restrictions and regain access to the computer. After paying the attacker, your system and data will be restored to their original state.
There are two general types of ransomware to notice. The first is the locker ransomware, which restricts access to the computer or infected device. The second is the crypto ransomware, which restricts access to files and stored data.
Ransomware is very annoying and could damage to your PC, then how to prevent ransomware? Read this post carefully to get some useful tips to prevent it.
Malware is also a combination of two different types of attacks. This usually means combining worms or Trojan horses with malware or adware. That is to say, the malware program appears to be a Trojan horse to you, but once executed, it will attack other victims over the network like a worm.
To remove these types of malware attacks, you must start with anti-malware scanning and remove the control components from memory.
8. Trojan Horse
Trojan horses pretend to be normal, harmless files or programs that enter your system to trick you into downloading and installing malware. Once you have installed a Trojan horse, cybercriminals will access to your system.
The most popular type of Trojan is a fake antivirus program that will pop up and claim that you have been infected, and then instruct you to run the program to clean your PC. It’s hard to defend against Trojan horses.
A zombie program is a computer infected with malware, so hackers can control it remotely. The zombie program can then be used to launch more attacks or become part of the zombie program collection. Botnets can spread millions of devices because they will not be discovered.
Botnets can help hackers carry out various forms of malicious activities, such as DDoS attacks; keyloggers, screenshots, and webcam access; send spam and phishing emails; spread other types of malware.
