How can I tell if I have a spam going out
I just received an undeliverable message from yahoo, that I was not the one who sent. How can I tell if my thunderbird has been hacked to send spam?
The message I received was:

There are some people who amuse themselves by being irritating and offensive. They either do not know right from wrong or they do not care. They abuse other people's email addresses, using them to send out loads of spam to a load of people they do not even know.
The first you get to hear of it is when one of those emails gets bounced back and of course it will get bounced back to you as it was your email address.
Do not bother responding to them. Delete the emails (unless you need to keep one for sending to ISP etc). As you have no idea who received one of those bogus emails, suggest you create a signature that you use for sending emails. Send an email to your friends and family, informing them that someone has been abusing your email address and in future they can tell the email is really from you by the signature. Usually you tell when it is not from the person you know as the email will read differently.
After a while the abuser usually gets bored and stops.
If you are concerned, you should first restart computer in Safe mode and then scan computer for visus etc. When you have the all clear, change passwords to webmail accounts and then update in Thunderbird.
If a load of emails have gone out in your name you could also contact your ISP (or google if a gmail account) to see if they have some record. After all you do not want to get blacklisted. They may ask you to supply information such as a copy of the source code of the bounced email.
Note; email addresses are often gleaned from websites, forums etc. It is advised, you should not post your email address in any public forum.
