Beware, we are just a day away from FBI to reshuffle around thousands on internet next week, but all you can do is you can save your system before it hits you. Mozilla has developed an easy “are you infected” websites. There are quick ways by which you can determine if you are infected with DNS Changer. What you can all do is to see by following the simple instructions and see if they might be infected.
In order to check, say for example, all you have to do is visit the link and will determine whether your system is infected or not. If it shows green, then you are not infected, and if red, then your system is, but yes before this thing happens to you, you can even also have the cure for this (instructions are here), but before you start fixing the problem, make sure you have a backup of all of your important files, so that accidentally it will not get away.
