Computer Security Exam Quiz: Trivia!

Using an antivirus program is indeed one of the more effective ways to protect against computer viruses. Antivirus software is designed to detect, prevent, and remove malicious software, including viruses, from computers. It scans files and programs for any suspicious activity or code, and if a virus is detected, it can quarantine or delete it. Regularly updating the antivirus program ensures that it stays up-to-date with the latest virus definitions, enhancing its ability to detect and protect against new threats. Therefore, using an antivirus program is crucial in safeguarding the computer and its data from potential virus infections.

A computer running slow can be an indication of a virus because viruses can consume a significant amount of system resources, causing the computer to slow down. When a virus infects a computer, it can perform various malicious activities in the background, such as running unwanted processes or using up memory and CPU power. These activities can result in decreased performance and slower response times. Therefore, if a computer is running slow, it is possible that it has been infected by a virus.

Backing up files regularly is important because it helps protect against data loss. If files are not backed up and something happens to the device they are stored on, such as a hardware failure or a virus attack, the files may be permanently lost. Regularly backing up files ensures that there is a copy of the data stored in a separate location, reducing the risk of losing important information.

False. This statement is incorrect. A virus can be implemented in multiple files and can spread from one file to another, infecting the system or other devices. Viruses are designed to replicate themselves and spread through various means, such as email attachments, infected websites, or shared files. Therefore, it is essential to have proper antivirus software and take precautions to prevent the spread of viruses.

When a computer runs an infected boot program, it means that the program is executed and its instructions are carried out. In this case, the infected boot program contains a virus, which is a type of malicious software. As the program is loaded into the computer's memory, the virus is also loaded along with it. This allows the virus to actively operate within the computer's memory, potentially causing harm and spreading to other files or programs. Therefore, the statement "When the computer runs the infected boot program, it loads the virus into the computer's memory" is true.

A sudden change in the memory your computer has left can be a sign that your computer has a virus. Viruses can consume a significant amount of memory, causing a decrease in available memory. This sudden change in memory can indicate the presence of a virus, as normal computer operations typically do not result in such a drastic change. Therefore, the statement is true.

A host program refers to a piece of software that contains a virus attached to it. This means that the virus is embedded within the host program, allowing it to spread and infect other files or systems. Therefore, the given statement is true as it correctly identifies a software with a virus as a host program.

Computer viruses are not created by chance; they are intentionally developed by individuals known as creators or hackers. These individuals have specific motives for creating viruses, such as causing harm to computer systems, stealing personal information, or gaining unauthorized access to networks. The creation of computer viruses requires knowledge and expertise in programming and computer systems, indicating that they are purposefully designed rather than occurring randomly.

This statement is false because it is possible for a virus payload to be harmless. A virus payload refers to the harmful or malicious part of a computer virus that is designed to cause damage or perform unauthorized actions. However, not all virus payloads are harmful. Some virus payloads may be designed for research purposes, to test security systems, or to raise awareness about vulnerabilities. These harmless virus payloads are created with the intention of not causing any damage to the infected system.

This statement is false. Viruses can be spread through downloads from the internet. Downloading files or software from untrusted sources can expose a computer to viruses and malware. It is important to have antivirus software and to only download files from trusted sources to minimize the risk of virus infection.

Virus hoaxes are indeed false warnings about viruses that are spread through email and over the internet. These hoaxes often contain exaggerated or misleading information, causing unnecessary panic and fear among users. They typically urge recipients to forward the message to others, perpetuating the spread of false information. It is important to be cautious and verify the authenticity of such warnings before sharing them further.

This statement is false because viruses can indeed hide once they are implanted in a computer file. Viruses are designed to be stealthy and can use various techniques to hide their presence, such as encryption, rootkit functionality, and disguising themselves as legitimate files or processes. This allows them to avoid detection by antivirus software and continue their malicious activities undetected.

The statement contradicts itself. It states that pirated software poses no threat to computers, but then goes on to say that it should never be used because it is morally wrong. This implies that there is a threat, not only to computers but also to ethical principles. Therefore, the correct answer is False.

The statement suggests that the worm named Melissa was virtually a harmless virus. However, the correct answer is False, indicating that the statement is not true. This implies that the worm named Melissa was not harmless and potentially caused damage or harm to computers all over the world.

A virus is a potentially damaging computer program designed to affect your computer negatively, whether or not you have knowledge or permission, by altering the way it works. Therefore, the statement that a virus can only affect your computer with your knowledge or permission is incorrect.

Using the email preview can help prevent getting a virus on your computer because it allows you to view the content of an email without actually opening it. This way, you can identify any suspicious or potentially harmful attachments or links before taking the risk of opening them. By previewing emails, you can exercise caution and avoid inadvertently downloading or executing malicious files that could infect your computer.

The given statement is false. The Trojan Horse virus is a type of malware that disguises itself as legitimate software, tricking users into downloading and installing it. Once installed, it can perform various malicious activities on the computer, such as stealing sensitive information, corrupting files, or allowing unauthorized access to the system. Unlike the statement suggests, the Trojan Horse virus does not require specific information or actions to activate or explode. It can cause harm as soon as it is installed on the computer.
