General (General discussion, talk about anything.)
Sounds like a typical "Browser Hijacker".
First thing to do is go into Add/Remove Programs and look for any suspicious sounding software, usualy Toolbars and Search Tools are the cause. If you suspect your kids have a look for any MSN add ons or Extra Free Smilies . If you find any of the above uninstall them.
Next download and run some free spyware removal tools like AdAware, Spybot, A2, Windows Defender(Genuine Windows XP required for this one). Links to some of these are on this page.
