SSC CGL 2023 PYQ — Question 146

The correct answer is option 2 i.e. resident 

• "Resident viruses" are embedded in a system's memory so they can be reactivated if the original virus is deleted.
• These types of viruses embed themselves in a computer's memory and can execute their malicious code whenever the system is running, making them persistent and difficult to remove.
• If the resident virus is removed, it may attempt to re-infect the system when it is restarted or when certain conditions are met, ensuring its survival and continuity.
• This characteristic makes resident viruses particularly troublesome for computer security.
