Help!

What should I do? I'm now getting about 12 e-mails a minute (and this went on all yesterday, but it was about 1 e-mail per minute!) that are from the virus/worm, code-named W32/Sobig.F-mm The e-mails have subject headers that say things like:

"Re: Thank you!"
or
"Re: My details"
or
"Wicked Screensaver"

With file attachments.

How do I get this thing to stop clogging my e-mail account??? I'm afraid that my ISP may shut me down for receiving too many e-mails!!!

Thanks,
Adam.
