No.... Kaspersky has nothing to do with it.
And no the file doesn't "go away", the download window just goes blank when the download is complete. The file is still where you told it to be downloaded to. What is happening is normal.... it's just the way that Firefox does downloads by default... there is nothing wrong. You can make changes to suit your needs very easily by ticking or un-ticking the boxes.
