    On Monday, July 9, the DNS Changer 'internet blackout' will take place;
    hundreds of thousands of computer users could potentially be affected, if
    they don't take action now.

    A Sophos video explaining the issue is linked to the page below.

    DNSChanger Malware causes a computer to use rogue DNS servers in one of two

    1) It changes the computer’s DNS server settings to replace the ISP’s good
    DNS servers with rogue DNS servers operated by the criminal.
    2) It attempts to access devices on the victim’s small office/home office
    (SOHO) network that run a dynamic host configuration protocol (DHCP) server
    (eg. a router or home gateway). The malware attempts to access these
    devices using common default usernames and passwords and, if successful,
    changes the DNS servers these devices use from the ISP’s good DNS servers
    to rogue DNS servers operated by the criminals. This is a change that may
    impact all computers on the SOHO network, even if those computers are not
    infected with the malware.

    The DNS Changer Working Group (DCWG), a cross-industry team of experts, has
    created a number of websites which offer to tell you automatically if your
    computer might have been affected by the DNS Changer malware. The DCWG test
    page site is also linked below.
