Maybe, M$ changed something in their fill-up form. I haven’t tried this for some time. I guess if you don’t get notification until 2, 3 days. Just try to contact m$ again and ask them what is happening.

Hope this helps

       –rwo, –report-warnings-only
              This option causes only warning messages to be displayed. This can be useful when rkhunter is run via cron. Other options may
              be used to force other items of information to be displayed.

       –sk, –skip-keypress
              When  the  –check command option is used, after certain sections of tests, the user will be prompted to press the return key
              in order to continue. This option disables that feature, and rkhunter will run until all the tests have completed.
