A virus is a program created by a programmer with the intention of causing harm to data or programs on a computer system. Unlike antivirus software, which is designed to protect against viruses, a virus itself is malicious and destructive. It can infect files and spread to other computers, causing damage and disruption to the system. Therefore, the correct answer is "Virus."

Viruses spread by using infected data because they are designed to attach themselves to files or programs, thereby infecting them. When these infected files or programs are shared or transferred to other systems, the virus spreads and infects those systems as well. This can happen through various means such as email attachments, downloading files from the internet, sharing files through USB drives, or even through network connections. Therefore, it is crucial to be cautious while handling data and ensure that it is from a trusted source to prevent the spread of viruses.

Booting refers to the process of initiating the computer and loading the necessary components for it to function. This includes loading the operating system, which is the software that manages all the computer's resources and allows users to interact with it. The operating system is responsible for coordinating the hardware, such as the processor, memory, and storage devices, to ensure that the computer operates smoothly. Therefore, the correct answer is the operating system.

When updating antivirus software, it is necessary for the computer to be connected to the internet. This is because antivirus software requires access to the internet in order to download the latest virus definitions and updates. These updates are essential for the antivirus software to effectively detect and remove the latest threats and protect the computer from potential malware or viruses. Without an internet connection, the antivirus software would not be able to stay up to date and may not be effective in providing adequate protection for the computer.

USB stands for Universal Serial Bus. It is a standard interface used for connecting devices such as computers, printers, and cameras to each other. The term "universal" signifies its widespread compatibility and usage across different devices and platforms. "Serial" refers to the way data is transmitted in a sequential manner, one bit at a time. And "bus" refers to the fact that it allows multiple devices to be connected to a single port, creating a shared communication pathway.

It is important to scan USBs before using them to prevent any potential malware or viruses from infecting the device. Scanning helps to detect and remove any harmful files or software that may be present on the USB. This precautionary measure ensures the security and integrity of the system and data.

A user with full access rights is an administrator. Administrators have the highest level of privileges and permissions on a system, allowing them to manage and control various aspects of the system, such as installing software, modifying settings, and creating or deleting user accounts. Standard users have limited access rights and can only perform basic tasks, while viruses and worms are types of malicious software that can cause harm to a system.

When the computer is turned off, the virus is removed from the primary memory, as it is a volatile form of memory that requires power to retain data. However, the virus can still remain on the hard disk, which is a non-volatile storage device that retains data even when the computer is powered off. Therefore, turning off the computer does not automatically remove the virus from the hard disk.

To protect your computers and network against threats, it is important to have Windows Firewall enabled. Windows Firewall acts as a barrier between your computer and potential threats from the internet or other networks. It monitors and controls incoming and outgoing network traffic, blocking unauthorized access and potentially malicious activities. By enabling Windows Firewall, you can significantly enhance the security of your operating system and safeguard your computers and network from various cyber threats.

Dropbox is a service that provides cloud storage, allowing users to store and access their files and documents online. It enables users to upload, share, and synchronize their files across multiple devices. With cloud storage, users can save their data remotely on servers, rather than relying on local storage devices like hard drives or physical servers. This allows for convenient access to files from anywhere with an internet connection, making it an efficient solution for file storage and sharing.

A Trojan Horse Program is a type of malware that disguises itself as a legitimate program or file, tricking users into downloading or installing it. Once inside the system, it can perform various tasks, such as stealing sensitive information, damaging files, or allowing unauthorized access to the system. Unlike viruses or worms, Trojan Horse Programs do not replicate themselves, but they can still cause significant harm to the system. Therefore, the given statement accurately describes the nature of a Trojan Horse Program.

Avast Antivirus is the best software for catching and removing viruses with a buzzer sound from the system. Avast Antivirus is a well-known and widely used antivirus software that offers comprehensive protection against various types of malware, including viruses. It has a built-in feature that alerts users with a buzzer sound when a virus is detected, ensuring immediate attention and action. This feature enhances the user's ability to quickly identify and remove viruses, making Avast Antivirus an effective choice for virus protection.

A virus is a malicious software program that is designed to harm or disrupt the normal functioning of a computer system. However, the hardware of a computer, which includes physical components like the processor, memory, and hard drive, is not directly affected by a virus. While a virus can potentially damage or corrupt files stored on the hardware, it cannot physically harm the hardware itself. Therefore, the hardware of a computer is not vulnerable to viruses.

A worm is a type of malicious software that can self-replicate and spread across computer networks without any human intervention. It is designed to exploit vulnerabilities in computer systems and use them to create multiple copies of itself, infecting other computers in the process. Unlike viruses, worms do not need to attach themselves to a host program or file in order to spread. Instead, they can independently move from one computer to another, causing harm by consuming network bandwidth, slowing down systems, or even deleting files. Therefore, the given explanation accurately describes worms as a program that multiplies on its own to make multiple copies of itself.

The correct answer is "Cloud" because with an internet connection, data can be easily shared and collaborated on through cloud storage platforms. Cloud storage allows users to store and access their data online, eliminating the need for physical storage devices like hard disks, USBs, or external hard drives. Additionally, cloud storage offers the advantage of scalability, flexibility, and accessibility from any device with an internet connection.

Executable files are programs that can be run or executed by a computer. These files contain instructions that the computer's operating system can understand and execute. Since viruses are also programs, they can infect executable files by inserting their own malicious code into them. When an infected executable file is run, the virus code gets executed, allowing the virus to spread and potentially cause harm to the computer or its data. Therefore, it is important to be cautious when downloading or running executable files from unknown or untrusted sources to avoid virus infections.

WPA stands for WiFi Protected Access. This is a security protocol used in wireless networks to protect data transmission and prevent unauthorized access.
