Computer experts needed.............

[Dave Rifkin]

I have been experiencing a problem when I open up Internet Explorer for the first time. When Internet Explorer first opens to my home page I get a pop-up that says something about a "Search Provider Default" and the verbiage states that a program on my computer has been corrupted, yada, yada, yada. I close that pop-up and then a new pop-up appears and it's a "Manage Add-Ons" screen. I close that out and everything works fine.
I have run Spy-bot and have an up to date Anti-Virus program running on my computer but, this problem still persists.
Can anyone offer some suggestions on how to correct this? It doesn't really affect how the computer runs (as far as I can tell); it's more of a nuisance.

I have tried to attach a print screen of the pop-ups that are showing up but, the document is too large.
