IE error message

Whenever I click the start avast! antivirus button and avast loads, the simple user interface comes up and also the error message : “An ActiveX control on this page might be unsafe to interact with other parts of the page. Do you want to allow this interaction?”. No matter what I click it still comes up. It also comes up whenever I turn on my computer from a complete shutdown, perhaps from when avast loads. Any help would be appreciated.
