Random Text Box Just Appearing On Desktop???

I have three computers in my house, all running Vista, all on the same network. I have recently had Verizon FiOS put, although I'm not sure if this is the cause or not. On two of the computers, about once a day, this random text box will pop up on the desktop. All it looks like is a small, blank internet browser window. It gives the current date at the top, but says nothing else. I have run through scans on both computer with Webroot Spysweeper w/ Antivrus, which I have found to be a great program for rooting out malicious software, but it finds nothing.

I just can't figure out what this random window is. Also, you can't "x" it out. Only way to get rid of it is to open Task Manager and manually end the task. I have posted a screen shot of it. It seems these computers started doing this after I got FiOS installed, but i'm not positive. What could it be?

It's actually an HP specific problem.

Now I just installed IE8 and it hasn't done it yet, so maybe that fixed it. If not, then I will try what this person did. I'm just posting this link in case anyone ever reads this and has the same problem...seems to be the solution.
