  • Question

  • Dear people,

    I have bought a 2nd hand pc which contained seriously infected files with some kinda virus..

    Even after hard format a virus still return, I found the virus with a debugger, and I tried to

    replace/paste the "renewed" dhcpcore.dll just out of curiousity..

    But Windows keep telling me that I'm unable to replace the file cause I dont have the

    permission (while logged in as fully ROOT/Administrator..

    So anyone, please help me out..
