Q: When reinstalling os x  what if disk util gives kernel errors

I have a virus that seems like it has created a HD with in the HD and the people penetrating  my MacBook  pro have created a tunnel or link into my computer. I was trying to just replace the HD completely but I see errors popping up that make me  nervous so I stopped. Any advice?  I belive I have found some of it but it's hard to tell, they've changed sudoers file to all privileges for all. They seem to have gotten into Keychain app, modified key tool, they either installed or modified javavm.framework, modified cvms root, also installed a larage number of frameworks...need I go on?

MacBook Pro with Retina display, OS X El Capitan (10.11.3), model# A1502
