VIRUS Full Form

What is the full form of VIRUS?

The full form of VIRUS is “Vital Information Resources Under Siege”. A computer virus is a computer program or code that is downloaded onto a computer without the user's knowledge or consent. The virus has the property of replicating and spreading from one computer to another. Successful replication can affect data files, hard disk boot sectors, and so on. The exaggerated area is said to be infected. Viruses are typically man-made programs created to access personal information, destroy data, or display political or funny messages on the user's screen. It spreads by infiltrating the host program and executing the infected program. Computer viruses cause billions of damages each year. Most viruses target systems running Microsoft Windows. To combat viruses, programmers have developed antivirus programs.

What is Virus?

A computer virus is a computer program or code downloaded to a user's computer without the user's knowledge and runs against the user's consent. Viruses have the ability to replicate themselves and spread from one computer to another. Successful replication can affect data files, hard disk boot sectors, etc. The affected area is said to be infected.

Viruses are man-made programs commonly created to access personal information, destroy data, or display political or humorous messages on the user's screen. It spreads by injecting itself into host programs and executing infected programs.

Computer viruses cost billions of dollars each year. Most viruses target systems running Microsoft Windows. To combat viruses, programmers have developed antivirus programs.

Effects of Computer Virus

1. Computer viruses can affect rated performance and can cause an explosion if ignored.

2. Some of the most powerful viruses can affect and damage files on your computer. It may also be deleted from your computer's memory.

3. Your computer's boot sector can also become corrupted.

4. Your computer's hard drive may have been compromised or completely wiped.

5. These viruses can also cause some programs to stop responding. This is how they lead them to total corruption.

6. Can perform a quick hack to steal information from your Personal Computer (PC) and transfer it to the hacker's computer.

7. Unattended viruses can cause unanswered messages and notifications to appear on your computer screen.

Different Types of Computer Virus

There are many types of computer viruses, each of which affects computers in different ways. Computer viruses move with technology and take many new forms. Here are some types of computer viruses:

1. Virus files:

File viruses are also called parasitic viruses because they damage all files but keep the host safe. It usually affects files with a .com or .exe extension. You won't even notice that this virus is running. Change the start of the program so that control falls to that code.

2. Boot Sector Virus:

Infects the computer's boot system. This type of virus runs every time the system is reloaded or rebooted. It is also called a memory virus because it does not attack the file system. These types of viruses now spread through physical means such as hard drives and USBs.

3. Macro virus:

This type of virus is mainly found in documents such as Word and MS Excel. Unlike all other viruses, this virus is written in a low-level language (such as C or assembly language). This type of virus usually spreads when files are transferred from one of her documents to another.

4. Multipart viruses:

This type of virus infects different parts of the system such as boot sectors, memory and files. It is contagious and spreads easily through computers. It's not easy to be there and see.

5. Resident viruses:

This type of virus stores itself on the computer and infects files and other documents. This virus corrupts the registry and interferes with the operating system.

6. Armored Virus:

This type of virus is encrypted, making it difficult for antivirus software to detect and manage it. It uses various techniques to persuade the antivirus to be taken seriously on the website, and uses methods that make the code more complex.

List of Malware

• Computer Worms: Computer worms: A worm is a virus that does not require activation of the host system and can spread throughout a network and on systems connected to it without user intervention.

• Trojan horse: These are computer programs that pretend to sneak onto your computer and deliver some sort of malware.

• Spam virus: Short for “malware spam” or “malicious spam,” malspam is spam messages that deliver malware to your device. Unsuspecting readers who click on links or open email attachments are infected with some type of malware, including ransomware, Trojans, bots, information thieves, crypto miners, spyware, and keyloggers.

• Spyware: Spyware is a type of malicious software that is installed on an end user's computing device without his knowledge. It infiltrates the device, steals sensitive information and internet usage data, and transfers it to advertisers, data companies, or external users.

• Zombies: Zombie is a malicious program that is installed on a device and turns it into a "zombie" that attacks other systems. A computer or other device modified by zombie malware is first infected with a virus or Trojan horse.

Requirements for Computer Viruses

A computer virus has certain requirements to become active. In other words, computer viruses require a host program and user action to spread from one system to another. Computer viruses usually append parts of their malicious code to other files, or even replace entire files with copies of themselves.

Myths regarding Computer Viruses

Computer viruses are very common these days, but there are certain myths associated with these viruses. For example, the

1. The error message you see on your computer does not necessarily indicate a virus infection, but could also be caused by a hardware or software error.

2. Malware and viruses are commonly spread via mass mail to contacts on infected computers. So be careful before opening any email attachments.

3. No user interaction is required to enable viruses and worms. Viruses may need to activate host files as part of an automated process, whereas worms are free to run, self-control, and spread without human or automated triggers.

4. Antivirus programs provide very comprehensive virus control, but they do not protect your computer 100% from viruses.

4. Download programs from official websites or trusted third-party sources.
