HiJacker infected all computers on our local network!

[elmodud]

I found a hijacker that would re-direct search requests from Yahoo and Google on one computer in our house and a few hours later found it had spread to all seven computers in our house. These computers were all on the same local area network. I've run spybot and Avira which both pick up nothing. I've also turned off all computers but one and tried a restore to no avail.

Below is a the dds log for one of the computers that is infected:

Is it possible for a hijacker to spread on a local area network like this? Please help - this is blowing my mind.....

[elmodud]

I researched this problem further and found the exploit. The virus got into my router (standard netgear with factory password) and changed the dns servers to their infected servers. They could then look at and redirect any internet link request they wanted on any computer that was using my network.

I was able to change the dns settings to the correct values and the hijacking stopped on all computers on the network!

A word to the wise: Change the password on your router from the factory default!!!!

I still need to determine which computer is infected with the bug that modifies the router settings. I will repost if I need help with it....

Thanks,

elmodud
