Hello. Don't worry, this directory is supposed to be here. Kinda. 

These files were created by a script ran by one of your friendly Tier 1 Agents, who you may have spoke with on the phone, in a chat, or over email. 
Or maybe you just submitted a request to buy or renew your SSL certificate. 

All in all, this folder and these files should only by here as an indirect result of you (or someone allowed to access your account.) requesting or renewing an AAL certificate. 

The script may have failed to remove these after it was done..
Thanks for understanding, you can safley delete this whole folder, as none of these files are needed after the SSL ins installed.
