UGC NET Questions (Paper – 1)

Statement D is the only wrong statement because Internet connectivity actually increases exposure to malware instead of ensuring immunity. Statements A, B and C correctly define malware, emphasise the value of antivirus software and warn about risky attachments. No technology can make a system permanently immune to all attacks; continuous vigilance and updates are needed. Therefore the option that selects only D as wrong is the correct answer.

Option A:
Option A is incorrect because it groups A and D as wrong statements. Statement A is accurate in using malware as an umbrella term for various malicious software types. Including this correct statement among the wrong ones makes the option logically inconsistent.

Option B:
Option B is correct because it isolates D as the sole incorrect statement while accepting that A, B and C are valid security guidelines. It underlines that connecting to the Internet does not eliminate risk and that protective measures remain vital.

Option C:
Option C is incorrect because it labels C and D as wrong. C is true, as attachments from unknown senders frequently carry malware or phishing attempts. Combining one true statement with a false one produces an invalid set.

Option D:
Option D is incorrect because it treats B and D as wrong statements. Statement B is a sound recommendation about antivirus use, so grouping it with the false claim in D misrepresents good security practice.
