I got a pm Today and it said this:
Check out the new Newgrounds' Desktop Application! It runs seemlessly for both X.P. and Vista users, and it allows you to stay updated with your favorite authors, watch flash from your desktop, or simply edit your account easily from your desktop. Check out stats of your, and others', flash movies using this helpful app, too. Made using the Newgrounds.com A.P.I.
And It contained a Backdoor trojan. The user name who sent it was: rsdevteam, If you get a Pm like this DON"T OPEN IT!!!
