Virus on my hotmail

Hi there,

 

I received a virus by email and now its automatically sending emails with virus to all my contacts. I scanned my computer and seems like Norton deleted what they have found. But I read on the internet its possible to scan also your email account but they didn't explain how.

 

Does anyone know how can I do that? Its the second time this happens in less than a month! Please, help me.

 

Thank you,
