OK. I am not sure short of reformatting the Windows machines. first you want to stop anything from pointing your web address into another direction. So go to OpenDNS.com and follow the directions for changing the DNS (Domain Name Server) in YOUR ROUTER. OpenDNS.com will walk you through in setting up changing where you get your DNS names.

The best part of this service is it is FREE. I urge you to sign up for an account so your can block phishing sites as well as site YOU designate that you don't want your kids looking at.

Doing OpenDNS.com doesn't change anything in your computers and your kids will know nothing happened at all.

For your Trojan problems on the Windows machines, wipe them and reformat the machines. This is the only safe way of making sure you get rid of all the problems. Plus make sure you keep the latest VIRUS protection on the Windows machines. You can even get pretty good free ones like AVG.

Good Luck.
