What is computer virus in one word?
Definition: A computer virus is a malicious software program loaded onto a user’s computer without the user’s knowledge and performs malicious actions. It can self-replicate, inserting itself onto other programs or files, infecting them in the process.
What are the computer viruses?
In more technical terms, a computer virus is a type of malicious code or program written to alter the way a computer operates and is designed to spread from one computer to another. A virus operates by inserting or attaching itself to a legitimate program or document that supports macros in order to execute its code.
What are the 4 types of computer viruses?
Common Types Of Computer Viruses
- File-infecting Virus. A virus that attached itself to an executable program.
- Macro Virus. This type of virus is commonly found in programs such as Microsoft Word or Excel.
- Browser Hijacker.
- Web Scripting Virus.
- Boot Sector Virus.
- Polymorphic Virus.
- Resident Virus.
- Multipartite Virus.
Is Trojan Horse A computer virus?
A Trojan horse or Trojan is a type of malware that is often disguised as legitimate software. Trojans can be employed by cyber-thieves and hackers trying to gain access to users’ systems. Users are typically tricked by some form of social engineering into loading and executing Trojans on their systems.

- Contain a protein coat called the capsid.
- Have a nucleic acid core containing DNA or RNA (one or the other – not both)
- Capable of reproducing only when inside a HOST cell.
Is virus a living thing or non living thing?
Viruses are not living things. Viruses are complicated assemblies of molecules, including proteins, nucleic acids, lipids, and carbohydrates, but on their own they can do nothing until they enter a living cell. Without cells, viruses would not be able to multiply. Therefore, viruses are not living things.
What are the two main parts of a virus?
The simplest virions consist of two basic components: nucleic acid (single- or double-stranded RNA or DNA) and a protein coat, the capsid, which functions as a shell to protect the viral genome from nucleases and which during infection attaches the virion to specific receptors exposed on the prospective host cell.
Why table is a non-living thing?
Answer. The table is a non-living thing because it cannot breathe, eat and cannot exhibit anything like the living beings. This is a non-living being because it cannot act like a living being and also cannot do any things on its own. The table is not made up of cells which the living beings are made up of.
What is a non-living thing called?
