Malware labels sound similar when a question places viruses, worms, Trojans, spam, and phishing in one option set. Negative words such as "not" and "least" create another trap: you may know the concept but answer the opposite of what was asked.
The twelve questions below come from EMRS, KVS, DSSSB, NVS, RSSB, Bihar STET and UPPSC papers, and each section takes one distinction: safe practice against careless disclosure, digital infection routes against physical objects, antivirus products against malware families, and the firewall and multipartite definitions. Attempt every question before you read the explanation under it, which names the deciding clue and the distractor that comes closest. Read every negative word twice before checking the options.
Cyber-safe practices and online privacy MCQs
Start with actions a user controls: authentication, password handling, updates, and social-media disclosure.
Question 1, EMRS 2023
"Which of the following is not considered as a good cyber safe practice?"
(a) "Saving Passwords in a Text File on Desktop"
(b) "Using 2-factor authentication"
(c) "Changing Online Account Passwords Regularly"
(d) "Updating all apps/tools regularly"
Correct answer: (a), "Saving Passwords in a Text File on Desktop".
A desktop text file leaves saved credentials readable to a person or malware with account access. Two-factor authentication and updates add barriers, so option (a) is clearly unsafe. You can see this question in the Cyber Safety and Malware set.
Question 2, EMRS 2023
"Which of the following is considered as a good cyber-safe practice?"
(a) "Using 2-factor authentication"
(b) "Adding comments on every post regularly"
(c) "Uploading every trip’s photos on social media regularly"
(d) "Keeping same password for all accounts for ease of use"
Correct answer: (a), "Using 2-factor authentication".
A second factor can block account takeover even after a password is exposed. Password reuse spreads one breach across accounts, while frequent public posting can reveal personal details or travel patterns. See this question in the Cyber Safety and Malware set.
Question 3, DSSSB 2024
"Which among the following given below is correct in context of privacy issues in social media and online platforms?"
(a) "The sharing on social media especially by children must be monitored at all times."
(b) "The addiction of social media does not hamper the academic performance of a student."
(c) "Rumours and fake news cannot put the administration at risk."
(d) "Mishandling of social media cannot create tension in the law and order."
Correct answer: (a), "The sharing on social media especially by children must be monitored at all times."
Option (a) recognises that children need guidance before sharing personal details or locations. The other options deny genuine digital risks in absolute terms, so none is a sound privacy-safety statement. See this question in the Cyber Safety and Malware set.
Virus entry routes and physical-threat MCQs
Separate digital infection vectors from physical objects or events. Restate "not" or "least" before evaluating the options.
Question 4, EMRS 2023
"Which of the following is not a source of the virus entering your system?"
(a) "Hard disk"
(b) "Pen drive"
(c) "Printouts"
(d) "Email attachment"
Correct answer: (c), "Printouts".
A virus needs digital data or executable content to enter a computer. Hard disks, pen drives, and attachments can carry infected files, but paper cannot execute code. See this question in the Cyber Safety and Malware set.
Question 5, EMRS 2023
"Which of the following is the least threat for virus infection?"
(a) "Downloaded free software"
(b) "Downloaded email attachment"
(c) "Online printer"
(d) "Portable storage devices"
Correct answer: (c), "Online printer".
Free software, downloaded attachments, and portable storage can deliver infected files. An online printer is the least likely route here, though a networked printer still needs secure configuration and is not risk-free. See this question in the Cyber Safety and Malware set.
Question 6, Bihar STET 2025
"Which one is not a physical threat?"
(a) "Hacking"
(b) "Storm"
(c) "Fire"
(d) "Flood"
Correct answer: (a), "Hacking".
Storm, fire, and flood can physically damage equipment, power, or a site. Hacking is a logical threat because it targets systems and data rather than the physical environment. See this question in the Cyber Safety and Malware set.
Antivirus tools and early-malware MCQs
Separate defensive products from malware types, and hold on to one date: Creeper appeared in 1971.
Question 7, KVS 2023
"Kaspersky, McAfee, Norton, etc. are popular examples of:"
(a) "Anti Viruses"
(b) "Trojan Horses"
(c) "Spam Viruses"
(d) "Worm Viruses"
Correct answer: (a), "Anti Viruses".
Kaspersky, McAfee, and Norton are security products that detect and remove malware. Trojan horses and worms are malware classes, not defensive tools. See this question in the Cyber Safety and Malware set.
Question 8, RSSB 2022
"Which of the following is a first computer virus?"
(a) "Sasser"
(b) "Blaster"
(c) "Creeper"
(d) "Both (A) and (C)"
Correct answer: (c), "Creeper".
Creeper, written in 1971, was the first self-replicating program to spread between networked machines, and it is the answer computer-awareness papers expect here. Sasser and Blaster arrived decades later, which also eliminates option (d) because it includes Sasser. See this question in the Cyber Safety and Malware set.
Trojan malware and disguised-program MCQs
Smartphones and computers share one clue: malware disguised as something useful.
Question 9, KVS 2023
"This is a type of malware that we download onto our smartphones, disguised as useful apps or games, but usually take control of our smartphones to damage and steal our data."
(a) "Virus"
(b) "Spam"
(c) "Trojan"
(d) "Phishing"
Correct answer: (c), "Trojan".
A Trojan poses as a legitimate app or game so the user installs it voluntarily. Spam is unwanted messaging and phishing is a deception method, while this stem asks for the installed malicious program. There is no individual solution page for this one, so practise it inside the full Cyber Safety and Malware question set.
Question 10, KVS 2023
"These are the type of programs, we generally download onto our computer system, disguised as useful and free software, but take control of our computer systems to damage our data."
(a) "Virus"
(b) "Spam"
(c) "Worm"
(d) "Trojan"
Correct answer: (d), "Trojan".
The decisive phrase is "disguised as useful and free software", which identifies a Trojan. Worms self-propagate and spam is unsolicited communication, so neither matches this installed program. See this question in the Cyber Safety and Malware set.
Firewalls and multipartite-virus MCQs
Finish with exact definitions: firewall implementation and the two locations infected by multipartite malware.
Question 11, NVS 2017
"A Firewall is"
(a) "Only a software"
(b) "only a hardware"
(c) "a software with or without hardware"
(d) "necessarily both software and hardware"
Correct answer: (c), "a software with or without hardware".
A host firewall can run as software, while a network firewall may be an appliance combining software and hardware. Firewalls are not limited to one implementation and do not require both in every case. See this question in the Cyber Safety and Malware set.
Question 12, UPPSC Polytechnic Lecturer 2018
"What is multipartite virus?"
(a) "Hybrid of macro virus and stealth virus"
(b) "Hybrid of virus and worms"
(c) "Hybrid of ActiveX and Java control"
(d) "Hybrid of program virus and boot sector virus"
Correct answer: (d), "Hybrid of program virus and boot sector virus".
A multipartite virus infects both executable program files and the boot sector. Its name refers to multiple targets, not to a virus-worm mix or two browser-control technologies. See this question in the Cyber Safety and Malware set.
Cyber Safety and Malware MCQ answer-pattern review
Use the answer key to check your attempt, then return to the clue behind every error.
Question | Q1 | Q2 | Q3 | Q4 | Q5 | Q6 | Q7 | Q8 | Q9 | Q10 | Q11 | Q12 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
Answer | a | a | a | c | c | a | a | c | c | d | c | d |
The distribution is a = 5, b = 0, c = 5, d = 2. Option (b) never carries the answer here, which is a coincidence of these twelve papers and nothing more. Use the key to mark your attempt, never as a guessing rule: examiners do not balance option letters.
Suppose a learner gets 9 of 12 correct:
Correct answers = 9.
Total questions = 12.
Percentage = (9 / 12) x 100 = 0.75 x 100 = 75%.
If the misses are Q5, Q8, and Q12, the error log has one negative-wording miss ("least"), one history miss (Creeper, 1971), and one malware-taxonomy miss (program virus plus boot-sector virus). The next revision should target those three labels instead of rereading all 12 explanations.
On the second attempt, follow the timed and review sequence in Teaching Exam Mock Strategy for CS Papers. The principle in Computer Science Pedagogy for Teacher Exams also applies here: state the distinguishing clue in your own words instead of memorising only an option letter.
Cyber Safety and Malware MCQs: the short version and next step
Keep six distinctions clear: safe action versus unsafe disclosure, digital infection vector versus physical object, antivirus tool versus malware, Trojan disguise versus worm propagation, firewall implementation, and program-file plus boot-sector infection. These contrasts answer most distractors before recall becomes difficult.
