anti-virus bar cancelled continued dropped estimated file firewall interfering internet left minute minutes mp3 obviously progress security show slowing software song sounds speed stopped twenty twice upload uploading zero

I tried twice to upload an mp3 file of a 2.5 minute song. Each time, the estimated time left dropped to zero, but the uploading bar continued to show, the progress stopped at 99.96% and the upload speed kept slowing. I cancelled the upload after twenty minutes since something was obviously wrong. What should I do?

That sounds like your anti-virus/internet security software or firewall is interfering with the upload.
