I have the popup blocker enabled on my Firefox as well, but it doesn't appear to be a true pop up. It almost looks like an error message, but the actual page looks legit with the swagbucks logo on top, and all the Best Buy and Walmart advertizing too. It's very weird because I have swagbucks bookmarked so I know I'm not on a weird fake site, and I was just doing my dailies like always and went to NOSO. Once I got to the end and I did the capcha, got my points, but then it said I wasn't a winner. Went back to NOSO just to make sure and then got the winner notice. I'll wait to see what I hear from Swagbucks before I do anything. I'm sure if it were legit that Swagbucks would be advertising it, therefore if it's not, I wonder what is causing it and how I can get rid of it.

PS thanks for the reply. The swagbucks thread really tends to irritate me because people very rarely answer questions and just keep posting their wins.
