Check settings in your mail program, that you aren't leaving stuff on the server, and then dowloading it again , next time your program connects. If you have real problems with a dud email that wont clear, try using the ntl web mail to access and kill it off.

A virus on a computer will continualy try and send itself out, often with email that appears to be the same as others. If you are unfortunate enough to be in the address book of more than one infected puter you'll get deluged with infected mail.

As for Spam, don't think there is an effective answer. However, I havent had a spam on my ntl account for months. All I did was change my email addys to something that isn't readily guessed by the spammers.
