C:\Documents and Settings\Deven\AppData\Local\Microsoft\Windows\NetCache\Content.IE5\ECVD6FS\, which is odd since Win 8.1 does not have a Documents and Settings folder.
I had Kaspersky remove it. I ran Malwarebytes Anti-Malware to scan my entire hard drive, and it found nothing.
I am now running Microsoft Safety Scanner to triple-check. What else should I do? Thanks!
