If antivirus software is installed but has not been updated for a long time, what is its main weakness?

Answer and explanation

Correct answer: It may be less effective at detecting new threats

Antivirus programs rely on updated threat definitions, detection rules, and sometimes improved scanning engines. New malware may not match an old database, so an installed but outdated program can fail to recognise current threats. It does not normally delete every file, change RAM into permanent storage, or control the monitor in the ways described. Therefore, option B is correct.
