Symantec Antivirus Live Update has a problem of hang at 99% in Windows Vista. The live update is launched, download is done, and after I pressed Finish button, it gave a small pop-up window showing a progress-bar saying “Updating Virus Protection Files”, this progress bar hangs at 99% and remains at 99% for ever, I have to manually end the process, it becomes not responding.

I tried to find a way out, and it worked for me, in this post I am going to share the method by which I solved this issue.
