After confirming the removal of a virus from a computer, the technician should ensure and verify the full functionality of the system by:
- Checking for the latest operating system (OS) patches and updates to ensure the system is fully patched and secure.
- Testing the operation of the computer and the network it is connected to, verifying that all hardware and software components function properly.
- Running system integrity checks, such as using the Windows System File Checker (SFC) tool to identify and repair corrupted or modified system files caused by the virus.
- Reviewing the startup programs and processes to remove any leftover or unnecessary items that could slow down the system.
- Rebooting the system to confirm it starts up correctly and operates normally without virus symptoms.
- Talking with the user to confirm that the problem causing the virus infection has been resolved and the system meets their needs.
- Documenting the problem, the procedures performed to resolve it, and the verification steps taken to confirm full system functionality.
This systematic approach ensures the system is clean, fully functional, and protected against further issues after virus removal.
