When Council of Europe virus worms in a system through bugs/vulnerability/loophole/backdoor, drivers concerning security utilities and relevant services will be numerated to be overwritten with vicious codes. Further manipulations can thus be made deep in a system:
- Council of Europe virus puts its codes into boot sectors to ensure that it runs right before Windows every time.
- Startup items of Council of Europe virus will be injected into related entries to make sure that the counterfeit warning and “Bitcoin mining” botnet will continue to work.
