1. Dormant Stage: In this stage, the virus is inactive and does not cause any harm to the system. It is like a sleeping virus waiting for a trigger to activate.
2. Propagation Stage: Once the virus is activated, it starts to replicate itself and spread to other files or systems. This stage allows the virus to infect more and more systems.
3. Triggering Stage: This is the stage where the virus is triggered to perform its malicious activities. This can be triggered by a specific date or time, a specific action by the user, or a specific event on the system.
4. Execution Stage: In this stage, the virus carries out its malicious activities, which can include deleting files, stealing information, or causing system malfunctions.
5. Concealment Stage: After executing its malicious activities, the virus may try to hide itself to avoid detection. This can involve encrypting its code, changing its file name, or using other techniques to evade detection by antivirus software.
6. Payload Stage: Some viruses have a payload, which is the actual harmful action that the virus is designed to carry out. This can include deleting files, corrupting data, or stealing sensitive information.
7. Spreading Stage: In this stage, the virus continues to spread to other systems, either through infected files, email attachments, or other means of transmission.
8. Detection and Removal Stage: Once the virus is detected, antivirus software or other security measures can be used to remove the virus from the system and prevent further damage.
