There is a wpdnse folder inside the temp directory. I found this when I was deleting the temp files from the system. I found the folder inside it and when I delete the same it is created back again. I think this would be some kind of infection or many a threat. I am only using Windows Defender as antivirus in the system and recently the only new software installed on my system is Windows Media Player. I found the folder suspicious because it is created again on its own .
