The different types of computer viruses
What are computer viruses?
A computer virus is a type of malware that, once executed, replicates by inserting its code into other programs or files, in order to spread itself and damaged system. In many cases, a virus will cause harmful or negative effects to a computer system, such as data deletion, corrupting files, or even completely crashing the system.
What are the different types of computer viruses?
There are numerous types of computer viruses, and new ones are constantly being created. Some of the most common types include:
Boot Sector Virus: A boot sector virus is a virus that infects the boot sector of a hard drive. This type of virus is particularly difficult to remove, as it can infect the boot sector even if the hard drive is reformatted.
File Infector Virus: File infector viruses areOne of the most common type of virus, file infector viruses infect executable files, such as .exe files. When these files are executed, the virus will replicate and infect other files on the computer.
Macro Virus: A macro virus is a virus that is written in a macro language, and is often embedded in documents, such as Microsoft Word or Excel documents. Macro viruses can be very dangerous, as they can be spread simply by opening an infected document.
Multipartite Virus: A multipartite virus is a virus that can infect both files and boot sectors. This type of virus is particularly difficult to remove, as it can spread itself in multiple ways.
Oligodynamic Virus: An oligodynamic virus is a virus that is only able to infect a small number of computers. This type of virus is not as common as other types, as most viruses are able to infect a large number of computers.
Polymorphic Virus: A polymorphic virus is a virus that is able to change its appearance, making it difficult to detect and remove. This type of virus is particularly dangerous, as it can evaded detection by anti-virus software.
Resident Virus: A resident virus is a virus that stays resident in memory, and replicates itself when certain conditions are met. Resident viruses are particularly dangerous, as they can remain on a computer even after it is rebooted.
Stealth Virus: A stealth virus is a virus that uses stealth techniques to avoid detection. Stealth viruses are particularly dangerous, as they can evade detection by anti-virus software.
Trojan Virus: A trojan virus is a virus that masquerades as a benign program, in order to trick the user into executing it. Once executed, the trojan virus will perform its payload, which can include anything from deleting files to stealing data.
Worm Virus: A worm virus is a type of virus that is able to spread itself without any user interaction. Worm viruses are particularly dangerous, as they can spread quickly and infect a large number of computers..Find Out More
