I've been receiving batches of 'Delivery Status Notifications (Failure)' from
[email protected] (eight at 00:50 to 00:55, four at 02:53 and one at 12:52).
Each one has an attachment (which I haven't opened!) and were addressed to addresses that I don't recognise - ie not from my address book.
I also notice that my 'sent messages' contain about the same number (maybe more) of emails sent at the same times (00:52 and 02:53) with the subject line 'Career Builder / Job for you ID #1328583 etc' - also to addresses that I don't recognise (not from my address book).
I've run Malwarebytes and it detects no problems, but it doesn't scan my Hotmail account (as far as I know).
How can I check whether I have been infected?
Is there a means of scanning a Hotmail account and removing any malicious 'scripts'?
