A computer virus has four legitimate phases: dormancy, propagation, triggering, and executing. The virus is dormant and waits for an event to activate it. During the propagation phase, the virus replicates itself and travels to further files or computers. Once active, the virus starts to do its destructive work. The virus carries out its malicious activities, which may involve wiping data, damaging files, or stealing personal information.
