Thanks for response. I'm using Avast version 4.1 Home Edition. Yes the installation appears to have worked fine from the outset until this particular problem happened. I would receive notices (from a little blue box that would appear in the lower right hand corner of my screen, above the taskbar) advising me of automatic updates. As I indicated in the original message, upon a reboot, that same little blue box advised me to click on the box to install something (an upgrade or a new version ??). I don't recall exactly what it said, but as I indicated, my screen was frozen. After a reboot, I right clicked the icon, clicked un UPDATING and then clicked on both AVS UPDATE and PROGRAM UPDATE (separately). Each time a dowmload screen would appear, but nothing happened. Subsequently, a new screen would appear telling me;
"SERVER WWW.AVS.COM(UNKNOWN 80) IS DOWN. THE SERVER IS INACCESSABLE BECAUSE OF A NETWORK ERROR OR MAINTENANCE / YOUR HTTP PROXY SETTINGS ARE INCORRECT / YOUR NETWORK SETTINGS ARE INCORRECT."
I have no idea if I operate from behind a proxy. I am connected via cable and I use Outlook Express.
Thanks for any help you may provide in resolving this issue.
