Some malware apps and viruses change the local hosts file so you can't
reach Windows update and virus definition web sites. If you're on XP
look in
C:\WINDOWS\system32\drivers\etc
and look at the file called "hosts." Open it with a tex editor, it
shouldn't have anything other than the following
----------------------------------------------
# Copyright (c) 1993-1999 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host
name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
127.0.0.1 localhost
--------------------------------------------
and if any lines reference anything.microsoft.com delete them.
If you find suspicious hosts entries, delete them and then reboot (or
type nbtstat -R from the command line) and see if that helps.
