that's stupid that they would actually think any one would pay. just hit alt+crtl+del and in the task manager "end task" on the locker and then its all gone and you move on.
I have fixed a few of my friend's putters by doing that.
just to be safe delete your cookies if your not sure where you picked it up.
and when you restart the browser do not click "restore session" or you will just open the locker again.
