Removal of McAfee from OSX

Note: This was written in 2015, it may be out of date now.

There are a lot of commands here which I use sudo if you don't know what you're doing with sudo, especially where I rm you can severely screw up your system.

There are many reasons which you would want to remove a piece of software such as McAfee, such as not wanting it to hammer your CPU during work hours which seems like primetime for a virus scan.

I intend this to be a living document, I have included suggestions from peoples' replies.

A more complete example (with rewriting cookie domains/paths) can be found at http://blog.haproxy.com/2014/04/28/howto-write-apache-proxypass-rules-in-haproxy/

We will try something roughly equivalent to the following ProxyPass directives in Apache2:

ServerName www.example.com
...
ProxyPass        /foo/  http://foo.local
ProxyPassReverse /foo/  http://foo.local

In haproxy.cfg we define a backend, say foo, to reverse-proxy to foo.local backend server.
