Spam mail being sent from my account.

I opened an email, I use Yahoo via Firefox, from what I considered to be a trusted source.

Next day I received a couple of people on my contacts list complaining that I had sent them spam emails. I checked my "sent box" but there was nothing in it.

Later I found a couple of Mailer-daemon failure messages for emails that I had not sent.

I immediately ran a full system scan via AVAST, which turned up nothing.

I have emailed as many people as possible telling them to ignore any email from me unless it contains certain words in the header.

What else can I do?

Any comments would be welcome.

Change your e-mail password and look in your contacts to make sure there are no unknown names in it.

Avast is anti-virus and may not pick up other types of nasty. Download and run the free version of Malwarebytes from this url:
