email infected ? Unsure

[pursuant]

A friend recently received an email from me that I did not send. The name was mine in the header but the actual email was something that didn't belong to me. Since then I received an email from  the same person with a generic message and a link to a web address. The address was blocked by my AV program. When I sent the reply back to her asking for affirmation that she sent it, it came back undeliverable and this information.

I am trying to determine if I am infected or if someone got my name and sent it in the header so it would be recognized by my friend? I am not sure what is going on.

Hello and welcome to Computer Hope Forum. My name is Dave. I will be helping you out with your particular problem on your computer.

1. I will be working on your Malware issues. This may or may not solve other issues you have with your machine.
2. The fixes are specific to your problem and should only be used for this issue on this machine.
3. If you don't know or understand something, please don't hesitate to ask.
4. Please DO NOT run any other tools or scans while I am helping you.
5. It is important that you reply to this thread. Do not start a new topic.
6. Your security programs may give warnings for some of the tools I will ask you to use. Be assured, any links I give are safe.
7. Absence of symptoms does not mean that everything is clear.

If you can't access the internet with your infected computer you will have to download and transfer any programs to the computer you're using now and transfer them to the infected computer with a CD-RW or a USB storage device. I prefer a CD because a storage device can get infected. If you use a storage device hold the shift key down while inserting the USB storage device for about 10 secs. You will also have to transfer the logs you receive back to the good computer using the same method until we can get the computer back on-line.

It appears that both email accounts have been hacked. You should both change your email passwords.

Why are you sending those logs to me? Do you have any other indications that your computer is infected? As I stated before your email account has been hacked. What email program do you use?

[pursuant]

I am using web based Gmail and Yahoo. I think you mentioned changing the pw on my accounts. I have done that with Gmail but am having a hard time with Yahoo.

[SuperDave]

Once you get all your passwords changed that should be the end of the hacking. Make certain that you use strong passwords. They should include a capital letter along with some numbers.

Thanks for the help. Unfortunately I still can't figure out how to change my Yahoo pw. I have an email into their support for help. And believe I have tried every source on the web trying to figure it out.

Thanks

I had the same problem last week helping a friend with Yahoo. Sorry I can't help much with that.
