A computer virus is a type of malware that, once installed on a computer, can replicate itself and spread to other computers. A computer worm is a type of malware that, once installed on a computer, can spread to other computers without needing to be attached to an email or other program. A Trojan horse is a type of malware that, once installed on a computer, masquerades as a legitimate program but instead performs malicious activities. Spyware is a type of malware that is installed on a computer without the user’s consent and that collects information about the user’s activities on the computer. Adware is a type of malware that displays advertising messages on the user’s computer.

What are the 6 types of malware?
Malware is a type of software that is designed to damage or disable computers and computer networks. There are six main types of malware: viruses, worms, Trojans, spyware, adware, and ransomware.
Viruses are the most well-known type of malware. They are self-replicating programs that spread from computer to computer by attaching themselves to other programs or files. Worms are also self-replicating programs, but they spread through computer networks rather than individual computers. Trojans are programs that appear to be something else, such as a useful program or file, but actually contain a malicious payload. Spyware is software that surreptitiously gathers information about users, often without their knowledge or consent. Adware is software that displays advertising content on the user’s computer. Ransomware is a type of malware that encrypts the user’s files or locks the user’s computer screen and then demands a ransom payment to unlock them.
While all of these types of malware can cause serious damage, ransomware is increasingly becoming a major threat. In 2017, ransomware attacks accounted for 43 percent of all malware attacks, up from just 2 percent in 2015. Ransomware can lock users out of their computers, encrypt their files, and even delete their files. In some cases, ransomware attackers have even threatened to publish the victim’s personal information if they don’t pay the ransom.
The best way to protect your computer from malware is to keep it up-to-date with the latest security patches, use a good antivirus program, and be careful about what programs and files you download and open.
What are five malware types?
Malware is a type of software that is designed to harm a computer system. There are many different types of malware, and it is important to be aware of them in order to protect your computer.
The five most common types of malware are viruses, worms, trojans, spyware, and adware.
A virus is a type of malware that attaches itself to another program or document in order to spread. It can damage files, slow down your computer, or even delete data.
A worm is a type of malware that spreads itself through networks and infects other computers. It can do damage such as delete files or crash your computer.

What are the 4 main types of malware?
There are many different types of malware, but some are more common than others. The four main types of malware are viruses, worms, Trojans, and spyware.
Viruses are probably the most well-known type of malware. They are small programs that can attach themselves to other programs or files and spread from one computer to another. Worms are similar to viruses, but they can spread without needing to attach themselves to other programs. Trojans are programs that masquerade as something else, such as a helpful program or a game, in order to get people to install them. Once installed, Trojans can allow other malware, such as viruses or worms, to spread or can steal information from the computer. Spyware is software that collects information about a person or organization without their knowledge or consent. It can collect data about what websites a person visits, what they type into their computer, and even their passwords and financial information.
All of these types of malware can cause serious damage to a computer or network and can even result in the loss of data or information. It is important to keep your computer and software up-to-date and to use antivirus and anti-spyware software to help protect yourself from these threats.
What is the most common malware?
Malware is a type of software that is designed to harm or disable computers and computer networks. There are many different types of malware, but the most common are viruses, worms, and Trojans.
A virus is a type of malware that can spread from one computer to another. It is a program that can attach itself to other programs or files, and can spread when the infected program or file is copied or shared. Worms are a type of virus that can spread on their own, without needing to be attached to other programs or files. Trojans are a type of malware that masquerades as a legitimate program, but actually contains a hidden malicious function.
All of these types of malware can cause a wide range of problems for computer users, including loss of data, theft of information, and damage to hardware. They can also allow other malicious programs to be installed on the computer, which can lead to even more serious problems.
Users can protect themselves from malware by using anti-virus and anti-malware software, and by being careful about what programs and files they download and open. It is also important to keep the computer’s software up to date, as many new malware threats take advantage of vulnerabilities in older software.
What are 7 types of computer virus?
There are many different types of computer viruses that can infect a computer system. Some are more serious than others, and some can cause more damage than others. Here are seven of the most common types of computer viruses:
1. Boot sector viruses: These viruses infect the boot sector of a computer’s hard drive. They are often spread through infected floppy disks or CD-ROMs. When the computer starts up, the virus is loaded into the memory and begins to infect other files.
2. File infector viruses: These viruses infect executable files, such as .exe and .com files. When the files are run, the virus is loaded into memory and begins to infect other files.
3. Macro viruses: These viruses are created by infecting macros in Microsoft Word or Excel documents. When the document is opened, the virus is loaded into memory and begins to infect other files.
4. Multipartite viruses: These viruses are a hybrid of boot sector and file infector viruses. They infect both the boot sector and executable files, and they can be very difficult to remove from a computer.
5. Polymorphic viruses: These viruses are designed to change their appearance every time they infect a new file. This makes them more difficult to detect and remove.
6. Stealth viruses: These viruses are designed to hide from anti-virus software. They do this by disguising themselves as legitimate files or by manipulating the operating system so that they are not visible.
7. Trojan horse viruses: These viruses are named after the Trojan horse from the Trojan War. They are hidden files that perform some other function, such as opening backdoors on the victim’s computer for other viruses to enter.
