HOST FILE; description and usage

  1. Bleeping Computer site has a nice tutorial on the host file and how it relates to
    DNS processing. Location (Macintosh, Linux, Windows), contents, and usage is explained.
    With all the *$&%^ advertising servers, the article also explains how special entries in the host file
    defeats access to adverts AND known sites with infected content.

    I might I that under the paragraph Block Spyware/Ad Networks
    there should be comments on misuse of contents! We have seen entries like
    which is the AVG home page. This entry (and any others which contain the url of a valid site but a bogus ip address)
    is a technique to hijack that site and could be used to phish the access to a bogus look-alike :(

    Controlling the contents of your host file is manditory!

    Is this a typo? The AVG home page is actually at

    It seems that malware will do that a lot, stuff like the following:

    That way people won't be able to update their antivirus definitions, and then additional malware can be installed but not detected.
