Email apparently from me

[kristell]

Hi people - wonder if you can suggest what I can do please?

This morning I received an email from a customer of mine asking me if I had forwarded her email to others as she has received a 'spam' email which was supposedly sent by me.

I did not do this.

There was no email sent in my sent folder

In my spam folder was about 10 undeliverable emails that had come back to me (although I had not sent them) which was the same as the email as my customer had received.

The email account is with Yahoo and I have sent it on to their abuse team.

Could there be something lurking on my computer? What can we do to ensure it is clean?

I appeciate your help with this - many thanks.

Hi

Yahoo email account has been hacked, but your computer is most likely fine. Change your yahoo password and this will take care of it.....

First off, make sure you have the latest version of Malwarebytes installed and updated then run a scan to make sure the system is not infected with something. Also run a scan with your updated anti-virus software. If no infections are found, then more than likely someone has hacked into you yahoo email account.

I would change your Yahoo email account password as soon as you can.

Have changed password and run the scan - this is the log - do you think everything is ok now?
