Well, if you want my advice, remove it immediately with all the programs that accompanied it on your PC and in "program files".
I got that bad experience last week and got the same nightmare. I know also a friend who got the same problem.
In fact, it adds maybe three or four other programs with it too which you must try to recognize, apart of lots of "cookies" and adds.
Attention: "Uninstall" will not remove everything automatically. You need to go to "Programs Files" and remove all the accompanied and related programs manually.
Try to pass "Add-aware" and "Spybot" after removing all of those programs and clean everything.
Good chance.
we have an arabic proverb which I don't know an equivalent to it in english. I like to add it here. It's in the meaning:
"Close the window from which you get the disturbing wind".
