Microsoft and AV sites not opening due to 127.0.0.1

  1. I have a laptop that cannot open any microsoft sites, or any AV sites.

    I ran a virus check using MSE and it came up clean.
    I installed Spybot S&D, it would not run, I managed to run it from the backup file it installs for instances such as this, and it came up clean too.

    I have checked the host file and all that was in it was a bunch of entries added by Spybot S&D. I replaced it with a default host file and I still cannot open any AV sites.

    If I ping these domains, I can see it is trying to reach 127.0.0.1

    Can anyone advise on how to remove whatever is blocking these sites.

    Thanks.

    The 127.0.0.1 address NEVER routes to anything outside your system. The HOSTS file entries
    with this address is a protection technique (ie these sites should not be access for whatever reason).

    When we install an A/V product, this address is typically used for the web-proxy service which
    operates like this:

    Code:
    browser or email - - - - - 127.0.0.1(Proxy Service)
                                      |
                               filter / protect access
                                      |
                                      +--- if allowed --------> ISP
                                                                            |
                                <---------------------------------+
    
    If you are seeing errors on 127.0.0.1, investigate your A/V (uninstall / reinstall recommended)

    you have to reboot if you change the HOSTS file contents
