Defender infinitely scanning

I've already contacted Live Chat yesterday about that. Defender is constantly scanning my site since the last update. If I hit "Cancel" button, it just restarts scanning. When it finishes, it sends me an e-mail with issues that aren't real issues (like php.ini files), but I can't access the settings page to fix/ignore anything, since when I open the Scan Settings Page, it is already or restarts scanning again. I would really need it working: don't want to go back to Wordfence that I've been using prior to Defender. Thanks.
