What is virus and types of computer virus
The computer virus extends itself to another code or other executable documents. The purpose of creating a computer virus is to infect vulnerable systems, obtain administrative control and steal sensitive data. Alligators design computer viruses with malicious intentions and prey on online users by tackling them. Read below for types of computer virus.
types of computer virus
Malware is types of computer virus that adds its virus code to increase it by changing the programs and applications. Computing viruses come in different forms to infect the system in a variety of ways. Some of the most common viruses are there
Boot Sector Virus
This types of computer virus are infected on the boot recorder and it is complicated to remove this virus and often requires the formatting of the system.
As the name suggests, macro-virus focuses especially macro-language commands in applications such as Microsoft Word. The same is also the same as other programs. However, as the years have gone, Microsoft Word has attempted to derogate by default in later versions. Therefore, cybercriminals began to use social engineering schemes to focus on users.
In the process, they trick the user and allow macros to launch the virus. Since macro viruses have come back in recent years, Microsoft has successfully rehabilitated by adding a new feature to the 2016 Office. This feature enables the ability to optimize macro-security managers. As a fact, it can enable reliable and barrier workflows if needed throughout the organization.
This types of computer virus are to change and re-write computer files. As the name says, the virus starts after the computer has been attacking overwriting files with its own code. On the flipside, transcription viruses can install new code in the files or applications that they sign up to spread the virus to additional files, applications, and systems.
More and more cybercriminals depend on the polymorphic virus. This is a type of malicious software that has the ability to change or mutate the source code without changing its basic functions.
When the security software detects a polymorphic virus, the virus modifies itself in this way, it is no longer detectable using the previous signature
This types of computer virus are implanted in the computer’s memory. Essentially, the original antivirus program is not required to infect new files or applications. Even after removing the original virus, you can activate the version saved in memory. This happens when the computer’s operating system loads certain applications or functions. Resident viruses are troublesome because they can go unnoticed by anti-virus and anti-malware software hiding in the system RAM.
A rootkit virus is a type of malicious software that secretly installs an illegal rootkit on an infected system. This opens the door for attackers and gives them full control over the system. An attacker will be able to substantially modify or deactivate features and programs. Like other advanced viruses, the rootkit virus is also created to bypass antivirus software. The latest versions of the main antivirus and antimalware programs contain rootkit scans.
System or Boot-record Infectors
Boot-record Infectors infect executable code found in specific system areas on the disk. As the name suggests, they attach to the USB memory and the boot sector DOS on floppy disks or Master Boot Record on hard disks. Boot viruses are not currently more popular because the latest devices rely less on physical storage media
