Malware has been known to modify your Windows HOSTS file to prevent you from getting help at an anti-virus vendors site. Perhaps this will help.

First check your HOSTS file located at

Windows XP = C:\WINDOWS\SYSTEM32\DRIVERS\ETC

Windows 2K = C:\WINNT\SYSTEM32\DRIVERS\ETC

Win 98/ME = C:\WINDOWS

Be sure and check-mark "Show Hidden Files and Folders" and uncheck-mark "Hide Protected Operating System Files" in your Folder Options first.

Open HOSTS with notepad. A 'standard" MS HOSTS file will look like this:

# Copyright 漏 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.
