Hello
I checked my C:\Windows\System32\drivers\etc folder. There is no SSL folder in this folder.
How did you get this folder? By installing specific software?
We could try to check the recycle bin for the deleted folder. Or try to restore the file with some specific hard drive file restore software.
Or try to copy it from other machines?
If the folder is installed with specific software, we may try to perform a repair install of the specific software or just reinstalled the specific software.
