    The last two have the inversr or the first twos ports so I would say that you
    are connecting to yourself and for some reason you are reverse dnsing to
    www.sophos.com. This would be something very dodgey in my mind, were there more
    connections then what you pasted?

  3. I could connect and browse around www.sophos.com okay. Seems like they
    are in the business of producing and selling security suites.

    You didn't download and install any evaluation software from their site or
    the Sony root kit unmasking tool by any chance?

    Sophos are a major antivirus company specialising in sales too large
    corporations, I dont know if they do individual AV. Dont know why you
    would be connecting unless you have installed one of their products or
    maybe used one of their virus removal tools.

    Dody indeed. When I ping www.sophos.com I get me!

    Pinging www.sophos.com [] with 32 bytes of data:

    Approximate round trip times in milli-seconds:

    But why the download traffic. Is it perhaps a trojan hiding behind a legit

    If I was an author of a backdoor I would consider a hosts file entry like that
    to make it impossible to update virus definitions on the compromised computer.

    Its normal to have connections from yourself to yourself, its how a lot of
    programs communicate with each other.

    Whats more worrying is why your machine now believes that it is sophos.com when
    its not.

    Goddamn. Something had rewrittten my hosts file and set all the AV sites to
    eg sophos
    avg etc

    Hence I could not browse them.
    What should my hosts look like now that I've deleted it.

    You should download updates to any antivirus package or install one as
    it is highly likely a virus has infected your PC.

    Normally there is nothing in the hosts file unless you are running a
    server on your PC or some add blockers use the hosts file to block
    downloads from advertising sites.

  10. Your hosts file is the least of your problems.

    You need to track down and remove all the viruses from your computer.

    It's usually easier to reinstall the operating system from scratch, especially
    if you are unfamiliar with virus removal.

    You've been infected by a Virus.
    Very common action by Virus's these days to modify the hosts file to prevent
    access to antivirus updates.
    Go into Safe mode.
    Delete the hosts file.
    Install Spybod search & destroy and use their hosts file (under advanced
    Then start looking for Virus's.
