What are the advantages and disadvantages of computer resident virus?

Computer resident viruses have the advantage of being able to infect files and programs on the host system without needing to be executed, making them more persistent and harder to detect. However, their disadvantages include the potential for significant system damage, data loss, and increased resource consumption, as they can slow down system performance and interfere with legitimate software. Additionally, they may go unnoticed by traditional antivirus software, complicating their removal and increasing the risk of widespread infection.
