Strange folder in D: drive

[Pilvinyymi]

A strange folder with "install.exe" file inside has appeared in my D: drive. I don't really know when the folder has appeared in there, but the drive should be completely empty since i haven't installed any programs in there. The folders name is just a combination of random letters and numbers. I also scanned it with Malwarebytes and fsecure and either of them did not detect any viruses. So i'm just curious what this mysterious folder could be.

My os is windows 10
