Which version of SEP are you using? Which operating system? Was a previous build of SEP on this machine before?
I have found that sometimes the Windows System account has incorrect values for proxy information, even if a proxy is not in use. It is not something that SEP has any control over, just usually comes to light because SEP utilizes the System account for things like scheduled LiveUpdate.
I recently encountered a case in which proxy information for the System account was incorrect despite setting it correctly with proxycfg, and I believe the explanation is
this:
...the Microsoft Windows HTTP Services (WinHTTP) proxy configuration tool, "ProxyCfg.exe".
...
The proxy settings for WinHTTP are not the proxy settings for Microsoft Internet Explorer. You cannot configure the proxy settings for WinHTTP in the Microsoft Windows Control Panel. Using the WinHTTP proxy configuration utility does not alter the settings you use for Internet Explorer.
This customer was able to correct set the proxy information using BITSAdmin per the example as given in
this blog:
If you need to change the proxy settings for the any of the system account like Network Service you can use the “bitsAdmin” command as shown in the following example:
bitsAdmin /Util /SetIEProxy NETWORKSERVICE MANUAL_PROXY [myProxy]:[myPort]
You can find the complete reference for this command at: http://msdn2.microsoft.com/en-US/library/aa362813.aspx
There is more information in the Solution of the following document about why this is occurring as of RU5.
