Email has been hijacked?

Here is a general guide:

Malware detected in email databases has to be cleaned up by you. You have a few choices:

1. delete the whole file which is not an option you normally want to use
2. load the email folder that contains the infection and delete ALL unnecessary emails (hoping to remove the problem email) and then use the Mailbox Cleanup option to delete all old emails. Then compact the Outlook database to permanently remove data. See http://support.microsoft.com/kb/196990 If you do not cleanup and compact the databases, the deleted emails may still be leaving hidden information in the database that you just cannot see but a scanner may still pickup on it.
3. create a new folder and move only emails you really need into the new folder and then delete the infected folder.

 

How are you locked out of your account? Are you saying that someone may have hacked into your account and changed the password? Is this an online email account? What is the email service you are using?

 

As stated in the general instructions for email infections, you need to delete everything that is in your email in box except for what you know is not infected. Another idea is to create an email contact such as:
aaa@aaa.com. But no scanner will find the problem as it really is only you that can find and remove the bad ones.

In the future, you need to use a different computer to change your passwords to be on the safe side.
