-## Frequently Asked Questions ##
+* Maintainers: [pluginkollektiv](https://pluginkollektiv.org)
 
-### Will AntiVirus protect my site from being hacked? ###
-Not literally "protect from". The plugin’s purpose is to *detect* any "hack" that has already happened and enable you to take immediate action upon it.
