The High sensitivity of the Standard Shield is scanning the files (email) downloaded and stored in your computer.
But, speaking technically, avast does not protect hotmail accounts because hotmail does not use pop3/smtp protocols to receive/send emails.

For other email accounts choose Internel Mail Provider or, if you use Outlook (not Express) the special plugin (MS Outlook/Exchange).

Hope it helps. Wellcome to forums.
