My Avast premium would find it but could not remove it. It did not show location to manually remove it. I moved emphasis on MOVED all Downloads and Documents to another drive that is for storage and no OS. Scanned the drive where I moved those 2 folders temporarily and the file was detected in my Documents folder with Avast premium and easily deleted. I also found that universalextractor.exe was the originator. Hope this helps others :>}
