Which term is defined as a virus that terminates and stays resident (TSR) in memory?

• A. Transient virus
• B. Intrusive viruses
• C. Worms
• D. TSR virus

Answer: (D)

The concept being tested is memory-resident malware. A virus that terminates its initial execution but remains loaded in memory to carry on with actions is described as terminate and stay resident (TSR). The term that matches this behavior is a TSR virus. It loads into memory and continues to operate without needing to relaunch, giving it persistence until the system is rebooted or the memory is cleared. This differs from a transient virus, which runs and then completely terminates; worms focus on network propagation rather than staying resident in memory; and “intrusive viruses” isn’t a standard term used to describe this specific behavior.
