If you’re having problems updating Avira Antivir Personal Edition (FREE antivirus software) it is quite probably because your computer, router, or ISP (Internet Service Provider) don’t fully support IPv6 (Internet Protocol Version 6) yet. If you are using Avira as your antivirus software and want a better method of updating your antivirus software automatically, follow these instructions…

1. Go to to “START” button and click on “RUN”.
2. Type “%SystemRoot%\system32\drivers\etc” and hit “OK”
3. Open the hosts file with Notepad.
4. Copy the 2 lines below and paste it to the last line at the hosts file. Save the file.
   
   2a01:138:a001:201::21 personal.avira-update.com
   2a01:138:a001:201::21 personal.avira-update.net

The contents of the Hosts file should now look like this:

# 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
2a01:138:a001:201::21 personal.avira-update.com
2a01:138:a001:201::21 personal.avira-update.net
