As you may gather this is the first time I have come across this one but way back in May we did make a note of it HERE which I read and then as I never came across it promptly forgot
Right then lets see if we can now clear it
Disconnect all systems from the router both wireless and ethernet then run MBAM twice on each system (including the laptop), once to kill it and once to be sure
I have just had a look at my netgear router and it has a small hole exactly as described so I would imagine yours is similar
It sounds like a case of Zlob/DNSchanger that change the router's DNS settings. I have yet to deal with a case like this, but from what I gather you must reset the router to its default configuration. This can be done by inserting something tiny like a paper clip end or pencil tip into a small hole labeled "reset" located on the back of the router. Press and hold down the small button inside until the lights on the front of the router blink off and then on again (usually about 10 seconds). If the user doesn’t know the router's default password, he/she can look it up HERE
However, if there are other Zlob-infected machines using the same router, they will need to be cleared before resetting the router. Otherwise, the malware will simply go back and change the router's DNS settings. The user will also need to reconfigure any security settings you had in place prior to the reset. Check out this site here for video tutorials on how to properly configure your router's encryption and security settings. They may also need to consult with their Internet service provider to find out which DNS servers your network should be using.
Your DNS value should be 22.214.171.124
Any questions then please shout - I am discussing this with other experts at the moment
