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
    1.1.1.1 www.grisoft.com
    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 grisoft.com.

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

    1.1.1.1 symantec.com
    1.1.1.1 grisoft.com
    etc...

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

    Cool.

    But did you mean girsoft.com? Or did you switch the i and the r intentionally?
