Ick... no.

There's no way to stop that except to change your email address.

And if they have a virus infected attachment, then it wasn't a person that sent it. It was from someone who got infected by a virus, and the virus in turn mails itself out to every email address it can find stored in that persons computer. Some of the better written viruses can collect email addresses from the people before it and modify itself to include those addresses when it infects the next person.

If it's just spam, then yes, someone is sending it to you on purpose. People get paid to send out spam email.
