Lately, when I turn on the wife’s computer, a window shown below pops up. This is even before I launch IE. I find that the first time I open IE, it cannot find the home page yet when I refresh it works fine. Moreover, I notice that when I open any page (via a link on one page), there is a brief nessage in the status bar that says something about downloading from res://C:WINDOWSsystem32shdoclc.dll/navcancl.htm then it opens the site I want.
Here is the error when I boot up.
