Depends on the type of virus.
Non-memory residential viruses have to interact with the user in order to infect a computer, meaning it needs to be clicked on by the user. Once the virus executes, it finds another program to infect, infects it, and then closes.
A memory-residential virus needs only to be activated once by the user and then puts itself in memory (RAM), so that way it does not need constant user interaction to execute the virus, which could slow down its reproduction rate. Whenever a program is launched, the virus intercepts the request and infects the program being opened, this way the virus spreads throughout the computer very fast.
