KIS Advanced Disinfection

I use to use KIS which has advanced disinfection technology, therefore it cures system file(s). However, Comodo only offers cure, which either deletes or quarantines files - if they are .sys files will that not render the system useless and unable to boot? I’m talking about CCE rescue disk etc.,

Thats an issue with Comodo. Dont know if they are working on disinfection atleast of system/critical files, technology or in the upcoming CIS version.
