Yesterday, I found a folder in my WindowBlinds file called DMist. The contents look like an ordinary WinBlind theme. I did not download it deliberately and it did not appear as a selection in the Desktop Properties/Appearance page. I deleted it. Today, it is back, again without any action from me other than running Stardock Central. Again, it does not appear in my list of installed themes. Can anyone tell me what this DMist is and why I'm getting it without requesting it?

Thanks
