I'm using IE 7 right now. I opened a new browser to check DP and I noticed after a few minutes that another tab had been opened and it was displaying an advertisment for a ringtone site. I doubt this was from DP, I'm guessing MSN as that's my homepage and I just didn't notice when I started IE. Just wondering if anybody's had that happen before? I didn't even see the second tab open.
You might have spyware, use ad aware to remove it. if its msn just switch your homepage to something like DP .
