The firmness of the rootkit was to foreclose the DRM software from beingness perceived and uninstalled - but there was an accidental side essence. The rootkit unsealed a instrument muddle on thoseputers that couldn't be perceived by touchstone certificate software, and near them vulnerable to attacks by spiteful software and hackers.
