What would be helpful would be what the virus warning is ?
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.
