Every time I run LiveUpdate, it signals the same error (8920,204) and fails to install the 'Virus Definitions' update (although it downloaded properly, and all other updates download and install successfully). I'd been using NIS 2011 (and before that, 07, 08, 09 and 10) without incident for several months before this occurred; scans show no viruses or threats that could have caused this. I have re-run LiveUpdate countless times, re-started my computer, un-installed and re-installed NIS, and installed an entirely different NIS from a new CD of NIS 2011; none of these have worked. I have also used the 'Intelligent Updater', which downloaded successfully, but failed to run because the file was supposedly 'corrupted'. The computer is a PC, running Windows Vista 32x and IE7. Could this be the problem? I have run NIS 2011 on another PC, running Windows 7 64x and IE8, without encountering any problems.
Any help would be greatly appreciated! Thanks in advance to anyone who replies!

I have checked my date, time and location settings, and all are correct. I'm not running any other security software, nor am I using proxy settings. I'm not running Vista SP2 - could this impact running NIS 2011?
Having SP 2 and IE 8 would increase the security of your computer. However, before you update to those, you need to have a clean computer. I am now thinking along the lines of perhaps malware is blocking the antivirus updates from installing since even the intelligent updater didn't work. I would try first a scan with the free version of Malwarebytes and see if that finds anything.
Download the free version, install and update then run a FULL scan. After the scan completes you should post the logs back to this thread.
It is a safer location to get the program from than malwarebytes themselves because some malware creators have large lists of sites that they block. Please be careful to down load the correct program ----the FREE version of MALWAREBYTES
(Thanks to Delph for providing the alternative site)
Please post your log if it shows any malware. Please come back and let us know how you made out. Thanks.
