Hosts
Online Armor will monitor the HOSTS file for any changes, and pop-up when an Unknown program attempts to modify the HOSTS file.
<![]() | The Hosts pop-up is very simple. The pop-up shows you the location of the Hosts file, the name and version information of the program that is attempting to modify the HOSTS file and allows you to choose to “Remember my decision” to prevent pop-ups if the same program makes additional changes to the HOSTS file in the future. You can click the small blue information bubbles next to a program's name to take you to the Online Armor website where you can view any information Online Armor has collected about this particular program.

Once a program has been allowed or blocked from modifying the HOSTS file it will be added to the Hosts list. You can access this list by opening the Online Armor Control Panel and selecting Hosts from the Main Menu.

The Hosts list is organized using a table with the following columns:
- Status – Shows whether the program was Allowed to or was Blocked from modifying the Hosts file.
- Program – The file name of the program file on your hard drive.
- Description – Shows the name of the program.
Each row is color coded to indicate whether the program is Allowed to modify Hosts (green) or Blocked is Blocked from modifying Hosts (red).
Below the Hosts list are the following buttons:
- Allow – Allows the selected program to modify your HOSTS file.
- Block – Blocks the program from modifying your HOSTS file.
- Add – Allows you to add a program to the list (the default when adding a program is Allowed). .
- Delete – Allows you to delete a program from the list.

You can also right-click any item in the Hosts list to perform the following tasks: 
- Allow – Allows the selected program to modify your HOSTS file.
- Block – Blocks the selected program from modifying your HOSTS file.
- Add – Allows you to add a program to the list (the default when adding a program is Allowed).

- Find – Allows you to perform a search to find a particular program's entry.
- Autosize columns – Sets the Keyloggers list to automatically resize all columns in the table to accommodate the longest string of text in each column. This makes it so that you can see all the text in the table without any information being truncated by the width of the columns and without having to resize the columns manually. This setting is enabled by default.
The Options tab contains the following two items:
- Legend – A visual reference to the color coding used in the Hosts list.
- Prompt when an unknown program attempts to modify the hosts file – Removing the check from this box will configure Online Armor to no longer monitor the HOSTS file. You can re-enable the feature again by placing the check back in this box.
