anytime anyone ever has a site they are going to visit, redirect you elsewhere, I would suggest to close out of your browser IMMEDIATELY. Don't click anything, don't scroll around, just close out of your entire browser by holding down Ctrl/Shift/Escape button, the task manager will pop up, make sure you're on the Applications tab or if you're feeling froggy, the Processes tab, and click any instance you see of your browser and choose End task. You may have several open, close them all.
The same goes for pop ups that come out of nowhere, telling you how your pc is full of viruses or the hard drive is failing. Don't click anywhere in any of the windows. DO NOT BELIEVE ANYTHING IN THE WINDOW.... if it has choices to Exit or Cancel or GO Back or whatever... you clicking ANYWHERE in that popup will install crap on you machine. I can't stress that enough.. DO NOT click ANYWHERE inside of a popup window, it's ALL BAD. The only safe thing to do is close your browser down or if you have to , shut your whole PC down.. just don't click anything trying to go back or close the window.
Now as far as this grifter dot org thing goes.... seems that belonged or belongs to a Team POISON member, who was outed by the infamous Anonymous offshoot LulzSec, who we've heard plenty about in the news over the past year.

So grifter dot org would not be a place I would necessarily feel safe to visit
