I'm afraid it is browser hijacking. Browswer hijacking is when your browser goes to a site that is not of your choosing.
Browser Hijacking: A browser hijacking occurs when a browser gets set to a website which is not the user's choosing. Sometimes information gets rerouted to another site without the user's knowledge and makes the Internet connection run slower. Hijacks can change a user's homepage

Maybe I can explain this by means of an analogy. Imagine that you are in Cape Town. You get in your car and you start driving to Durban. Only, your car starts driving on its own, the doors lock and you can't get out. When your car finally stops, you find yourself in Buluwayo. Your car followed the protocol the entire way, namely it stopped at all the red lights, gave the correct indications and kept within the speed limit. The only downside is you are now in Buluwayo instead of in Durban.
Would you be happy if your car did this? If not, why are you grateful when your browser does essentially the same thing? More than this, what if you took your car to the manufacturer to file a complaint and they tell you that they are very sorry, that's a user feature that the people from Zimbabwe requested. They didn't install anything on your car, or in your garage, it's a feature that they control from the manufacturer's head office in Port Elizabeth with a magic 8 ball and one $#@#$ magnet in Buluwayo.
Is your car being hijacked or is it being redirected? Do the semantics really matter or do you think it is acceptable for your car to drive somewhere you did not wish to go all by itself?
Frankly, I don't care what you want to call it but I will not like a car with a mind of its own. Likewise, I do not like my browser being redirected without my choosing.
This issue seems to be enjoying the attention it deserves so hopefully it will be resolved before next month. In the meanwhile I'm cashing in on people who are paying me to help them prevent this from happening to them. Thank you, iBurst. Soon, I'll have enough money to afford ADSL.
