In the what appears to be the default setting the following boxes are unticked:
Unattended Cleanup and Removal
Prevent any Changes to Configuration
Do not Shut Down Files Shares
Automatic Reset of Security Zones
Automatic Cleanup of Hosts Files
Which boxes should I tick or not tick?

Hi Kesher 
First of all, the default configuration is safe
But did you read the “BOClean Configuration” :
http://www.comodo.com/boclean/supboc.html#bocconfig
From here :

The “Configuration Options grouping” chapter descripes all the options you asked for
If you have questions after reading that, feel free to ask them
