Overwrite Virus

Types of Viruses – The metawriting virus is the most dangerous type that affects files in the computer, as it can destroy files. This dangerous virus is written above the file code on which the command locates in the computer. It results in a complete or partial change of the file’s content.

The meta-typing virus can work across many different operating systems which devices use, such as windows, Linux, and macintosh. If they spread significantly in device files. They may damage and disable them. One way to get rid of the meta-writing virus via a computer is to permanently delete and recover files infected with the virus through the backup. It has common types. Including Grog.377, Grog.202, Grog.456. The most dangerous form of metawriting viruses.

Macro Virus

The macro virus targets computers by adding their code to macros in different data files. Such as documents, spreadsheets, etc. And this type of virus causes changes to or clears the content of infected documents. While some forms of the virus reach the user’s email account. And send copies of infected files to all addresses on the user’s contact list.

Boot Sector Virus is the take-off virus, known as the boot sector virus. Changes the software for setting up the computer operation process. Which is store in the device’s hard drive or through other storage means such as floppy disks.

It is, therefore, one of the most dangerous viruses that a user’s machine may expose to. This type of virus spread significantly in the 1990s when floppy disks were commonly used among computer users. And although this type of virus may appear through portable drives and email attachments. Its prevalence has declined significantly with improvements in the structure of the primary input and output system.

Direct Action Virus

The mechanism of action virus is to move through the computer when you click on executable files, which are usually home or COM. Where the virus is located. And when you click on one of those files. Start to search for other files similar to the transmission.

Without clicking on such files. This virus does not prove itself and remains hidden through the device’s memory. This virus is considered a non-dangerous virus. It usually affects large files and the existing operating system. It should be distinguished that this kind of virus can be easily detected and removed through antiviral software.

Resident Virus

The resident virus is named after it because it remains permanently resident in the ram in the computer, to hide and store itself in it. This virus is a type of dangerous computer virus. As it can cause the infection of any file that runs on the computer because it holds its copy unit in the memory of the device to infect any file.

The resident virus exists in two different ways: the virus with rapid infection. Which causes severe damage to the device and quickly. So it can be observed that the device is infected with it. And the other form is the virus with the slow infection that spreads slowly throughout the device without being detected. And when the device infects with this type of virus it is challenging to get rid of it through various antivirus programs and may require the use of a virus expert to solve the problem.

Multipartite Virus

The multi-part virus spreads through the computer in multiple ways, as it tries to attack both the boot sector and the executable files or software in the computer. If the virus moves to the boot sector. The files in the device will be affected.

Vice versa, the injury of the files will infect the boot sector to damage the device. And also, to remove this virus from the computer.

Spacefiller virus vacuum filler virus. It is known as a cavity virus. It is a rare type of virus in its work. This virus fills itself into empty sections of files in the user’s device without changing its size. Making it more difficult to detect.

Polymorphic Virus

A polymorphic virus is a type of virus that can change shape every time it infects a new file. So it’s also called a stealth virus. This virus is one of the most challenging types of viruses that antivirus software can detect

Other Types of Viruses

Here are some different types of viruses that can infect the user’s computer: Directory virus, which infects pathways that indicate file locations via a computer. An encrypted virus is a virus that contains encrypted software commands that are copied and transmitted through the device.

A network virus is a virus that transmits through the local internet to which the computer is connected. As it usually uses resources shared between network devices.

File infectors is a virus that infects files on a computer when we convert them into exe files with the same original name as the file. And also, virus infection can spread slowly through the device when files are opened or are modified by the user.

Fast and slow infectors are a type of virus that avoids detection either by quickly infecting all system files. Often by transmission using the same antivirus software. So that they are spread when an antivirus program opens any file to examine it.
