As stated,, this is extremely odd. That window does only have one tab and opens on startup. You could be infected, but,,,, I haven't ever seen this.
There are only a couple places that this might be set at to run at start up....
One is the startup folder off the start menu
Also might check the public startup folder
And the default,, however, anything there should show in your startup folder,, hell check all the startup folders you can find.
The rest are in the registry... Be careful while in the registry, you can hose up your system.
Start / type Regedit in the search box and hit enter
Can you post what is listed there?
