What is multipartite virus give an example?
Specific reassortants were shown or suggested to have a higher fitness in segmented and multipartite viruses of animals and plants, such as, for example, Influenza virus, Bluetongue virus, Tomato spotted wilt virus, Cucumber mosaic virus, and several nanoviruses [31,33–39].
Who created the Ghostball virus?

| Original author(s) | Unknown |

What do you mean by companion virus?
A companion virus is an old type of virus that poses as a legitimate file by copying its file name but uses a different extension. It doesn’t modify files.
What is parasitic virus?
A Parasitic Virus, also known as a file virus, is spread by attaching itself to executable programs. When a program infected with a parasitic virus is opened, the virus code runs. To hide, the virus passes control back to the original program.
What is a overwrite virus?
Overwrite viruses. Some viruses are designed specifically to destroy a file or application’s data. After infecting a system, an overwrite virus begins overwriting files with its own code. These viruses can target specific files or applications or systematically overwrite all files on an infected device.
What is Ghost virus?
The Ghostball virus is the first known multipartite virus. It is a file-infecting virus that is capable of infecting COM files and disk boot sectors. The Ghostball virus was written based on code from two different viruses. The code that infects the COM files is inspired by a modified version of the Vienna virus.
What does the macro virus do?
Macro viruses work by embedding malicious code into data files, such as documents and spreadsheets. This code is activated as soon as these files are opened or when macros are enabled, proceeding to infect other files on your device. Microsoft Word documents are common carriers of macro viruses.
What is space filler virus?
CIH, also known as Chernobyl or Spacefiller, is a Microsoft Windows 9x computer virus which first emerged in 1998. Its payload is highly destructive to vulnerable systems, overwriting critical information on infected system drives, and in some cases destroying the system BIOS.
What is armored virus?
Armored-virus meaning A computer virus designed to be very difficult to reverse engineer and analyze. It is overly large, because it contains a large amount of misleading logic in order to foil attempts to figure out its mission.
What does stealth virus do?
When performing such tasks, antivirus programs detect the malware, but the stealth virus is designed to actively remain hidden from antivirus programs. It accomplishes this by temporarily moving itself away from the infected file and copying itself to another drive and replacing itself with a clean file.
Is there DNA in viruses?
A virus is a small collection of genetic code, either DNA or RNA, surrounded by a protein coat. A virus cannot replicate alone. Viruses must infect cells and use components of the host cell to make copies of themselves.
