Router settings changed by virus

A relatively new virus going round, logging in to customer's routers and changing DNS settings: computer users visiting Facebook, Google, Yahoo, YouTube, banking sites are being redirected to fake sites - even if the computer is virus free! This exploit can also affect non-Windows computers, mobile phones, consoles etc. Anything connected to your wireless router! If you are having trouble with these sites, your router may have been hacked. Some preconfigured routers, such as Sky and BT Homehub can be cleaned by holding the reset button but other affected routers will require a visit to sort the problem. Be careful about clicking on Facebook and Google links so that you are not affected!
