Weird PHP redirection
Here is the output from Live Http Headers:

    http://www.sitename.com/loginapplet.ws?mod=main&dest=maintenance.php

    GET /loginapplet.ws?mod=main&dest=maintenance.php HTTP/1.1

Does anyone have any idea what could be causing this?  My server doesn't even use Avast, and also, nothing in my application is causing this redirect internally..
