What Is a Resident Virus?

Resident viruses hide in memory and behave as if they are parasitic on various low-level functions (such as Interrupts). For this reason, resident viruses often cause greater damage to disks. Once the resident virus enters the memory, as long as the execution file is executed, it will infect it, and its effect is very significant. The only way to get it out of memory is to cold boot (turn off the power completely and then turn it on).
