Since I have set up hundreds of web servers in many many different configurations and have never once used that module I personally wouldn't hesitate to remove it. :) I wouldn't install it unless I had some specific configuration I wanted to do that required it. I haven't had a need up to this point. Having said that I see you having 3 options.
1) Remove the module as I stated previously
2) Disable the module by commenting it out the apache config file
3) Learn how to configure it and fix your existing configuration
Here is some more info on the module:
