Firstly I’m an avast user like yourself so there are some answers that I can’t give as I’m not an avast employee.

  1. not much else other than wait for it to be reviewed.

  2. are you using google chrome browser ?
    If so there have been times when the forums have been under load it causes a problem when trying to balance that load. For some reason or other this only seems to result in the index.php page being saved by the browser.
