So, you've clicked on a link from a file you found. Don't worry you have come to the right place...it's led you to a ransomware canary. 

Business IT Solutions have deployed this through a service called Huntress. Think of it like this - miners used canaries in coal mines to detect harmful gasses like carbon monoxide, likewise Huntress uses files like the below example to detect a harmful computer virus called ransomware. If this file is changed, moved, or deleted, it triggers an alert to Huntress and to us, about the possibility of a ransomware outbreak. It's important that you don't modify these files or their location in any way so they remain in place as defenders. They are typically hidden, take up minimal storage space, and they are safe.
