Virus in IE6 when the enter key is pressed?

Strangest thing started happening in IE6 about a two weeks ago.  Whenever the enter key is pressed in a form field, the following events occur.

1.)  The cursor disappears and the focus leaves the open IE window.  You have to click the mouse to get the focus to return to the open window and to continue typing in the form.
2.)  Nothing else visible happens. However, by using alt-tab, I can see that another instance of IE has been opened.  The target for that instance is https://3d-images.org/.  However, a window never opens.  If I alt-tab again, the other browser instance is closed.
3.)  The same happens if I use the enter key in the Address box, except that the focus automatically returns to my IE instance once the new page loads.

I have tried to de-install IE6, but it's not on the add/remove programs list, even after I removed the latest Service Pack.  I am running Windows 2000.  I don't know what event may have caused this to happen.  I do run McAfee, and it hasn't identified anything.  I am also running The Cleaner, which also hasn't recognized anything.  

I'm not sure if this helps, but here's the registration info for https://3d-images.org/:
