Apache2 is not wanting to be deleted - apache2

Question

I am having trouble removing a VirtualHost, so I thought of just simply editing the /etc/apache2/sites-available/default file. It turns out that I am trying to add the original 'index.html' file, which I have in the /var/www/ directory. But it is not working because another VirtualHost has taken port 80 and I don't see my 'index.html' file listed there in the default file. I am super frustrated, so I am thinking of just doing a fresh install of the apache2 service. But even though I use this command to remove it:
sudo apt-get install --remove apache2 php5 libapache2-mod-php5
Even though I do this, it is not removed and I get this error at the end of the process:
Errors were encountered while processing:
libopenvnc-imgproc2.3
libavfilter2:armhf
libav-tools
ffmpeg
E: Sub-process /usr/bin/dpkg returned an error code (1)
Is there any way to do a fresh install of apache2 along with php5 and libapache2-mod-php5 as I had installed them when I first got my Pi? I am just lost, I have gone to a million forums and none have helped me.....
Here is the 'default' file text:
NameVirtualHost *:8091
NameVirtualHost *:80
NameVirtualHost *:443
This is what I tried doing, but it didn't work, it said the file couldn't be found!
<VirtualHost *:80>
DocumentRoot /var/www/remote_replay.php
ServerName 192.168.1.80
</VirtualHost>
This part below works fine, but I want it removed!!!!!

There is a problem with your virtual host configuration, DocumentRoot must be a directory. If you want to serve a specific file, use DocumentIndex to specify the files to use in order of preference:
<VirtualHost *:80>
DocumentRoot /var/www/
DocumentIndex remote_replay.php index.php index.html index.htm
ServerName 192.168.1.80
</VirtualHost>
