You don’t mention what you are using for an email client as whocares asks ?
Unless you are using MS Outlook (not express) then the Outlook/Exchange provider settings are of no use.

I would also suggest taking these out at source rather than be dealing with them one at a time (treating the symptom as Targ57 mentions).

If you are regularly getting these infected emails, so as to be intrusive and not wanting to be notified about them, perhaps it is time to review your PC security. Rather than treat the symptoms, treat the disease. You can intercept these emails at source (your isp/services mail server) and delete them there, rather than download them.

I use MailWasher Pro, although it is primarily for Spam it is also easy to deal with suspicious emails. There is a free version, but this only works with a single email account. The Pro version works with multiple accounts.
