When Chrome browser execs cmd.exe as child process,
which popens McAfee as child,
so that McAfee's parent is cmd.exe
and McAfee's grandparent is Chrome,
I feel so really very strange!
An internet browser could write cookies to your harddisk,
a web browser could write cached data files to your harddrive,
a browser might read/write registry keys ( if proper implemented only to its registry area ) under Microsoft Windows,
but a browser should never ever start processes [ under Posix/unix a.k.a exec/popen/fork ] such as unsandboxed binary programs, (see WinAPI index)
that will running under users privileges with maximum users rights on local machine!
