Computer viruses are composed of four parts: the boot module, the infection module, the destruction module, and the trigger module. The "boot module" implements the introduction of the computer virus program into the computer memory; the "infection module" represents the infection condition judgment sub-module; The "destruction module" represents the condition judgment sub-module; the "trigger module" represents the judgment of whether certain specific conditions are met.
Computer viruses are composed of four parts: boot module, infection module, destruction module and trigger module.
1. Boot module (main control module): implements the introduction of computer virus programs into computer memory and makes the infection and manifestation modules active.
2. Infection module: The infection condition judgment sub-module determines whether the current system environment meets the infection conditions based on the infection conditions set by the boot module.
3. Destruction module (performance module): Performance condition judgment sub-module, based on the trigger conditions set by the guidance module, determines whether the current system environment meets the trigger conditions.
4. Trigger module: Before a computer virus is infected and attacks, it is often necessary to determine whether certain specific conditions are met. If it is met, it will be infected or attack. Otherwise, it will not be infected or will not attack, or it will only be infected but not attack. This condition is Computer virus triggers.
