Anyone Know where this file could be from VFDFix.exe it was inside a folder on my machine I had not seen before until I tried to use a folder from inside drobox called vault. I am not sure if dropbox created it but I do not think so because it was dated 2/25/2016. Any help would be appreciated. I think I should delete it or not. I dont like executable files when I dont know where its from. Thanks in advance. Windows 10 operating system.
