message blocked errors

This is a possible virus/spam query.

We have recently been getting a lot of 'message blocked errors' back through our e-mail system. These e-mails that have apparently been blocked have not been sent by us and are not to anyone we know. This leads me to think that either our computer/website has been hijacked by some malicious software which is using our account to send spam or this is just a new type of spam that we haven’t seen before and we should ignore it. Our McAfee virus checker has not picked anything up.

All email's have apparently been sent through our website using random letters at the start e.g. [email protected] (obviously not out real address)

I know how annoying junk mail can be so if our system is being used to send it out, I’d like to stop it asap.

OS: Windows XP
Other relevant software: Microsoft Outlook
