Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.

You can try these free programs to scan for malware, which work with your existing antivirus software:

• Microsoft Safety Scanner
• MalwareBytes' Anti-Malware
• TDSSKiller - AntiRootkit Utility

Microsoft Security Essentials is a good permanent antivirus for Windows 7/Vista/XP if you don't already have one.

Further information can be found in the Troubleshoot Firefox issues caused by malware article.

Did this fix your problems? Please report back to us!

Thank you iamjayakumars.

I tried Microsfot Safety Scanner yesterday and report was that nothing was found. I will try the other two that you recommended now and hope it works.  :))

I also downloaded Microsfot Security Essentials yesterday and deleted AVAST - am hoping it will make a difference and that this kind of thing won't happen again.

I will let you know if MalwareBytes' Anti-Malware and TDSSKiller - AntiRootkit Utility solve the problem.

Thank you again.  :)

Hello again iamjayakumars,

I tried MalwareBytes' Anti-Malware and 2 threats were found - both pup bundle installer 01. I quarantined and then deleted them but the spam emails continued.

This morning I ran the TDSSKiller - AntiRootkit Utility and 4 threats were found - all said: suspicious object, unsigned file, medium risk. I have deleted all of them.

Now to wait and see if the spam emails from own address come through again. I will keep you posted.  :)

Report the problem to your email provider, and change your password but do not store it on the computer.

If the problem is not that you have a spambot or other malware on your computer then someone else is accessing your email, or someone is spoofing your email information so that it appears to be you.

Hi John99,

Thank you for your input. I did report this to my service provider and they assured me that no one is accessing my account?

I also changed the password for the email addresses but not sure what you mean when you say I must not store it on my computer? One has to enter the password online in order to change and or access the account? I access via Outlook Express most of the time but go to Webmail every so often.

but not sure what you mean when you say I must not store it on my computer?

I was just thinking that if someone or some software agent is accessing your computer then they also have access to saved passwords if for instance it is webmail and the password is stored on Firefox, or if you store logins and passwords in any other utility.

An obvious thing to do is also make sure you log out of email and do not leave yourself logged in or use the remember me option.

Thank you for your input. I did report this to my service provider and they assured me that no one is accessing my account?  

I wonder what they meant by that

• possibly that the account has been accessed only from your computer and the same IP Address has been shown
• Maybe just that the mail used your login and password.

What are the emails ? do they make sense, are they also sent to others ? and of course is it likely anyone else is using your computer and sending these emails.

it is probably worth contacting them again, give a couple of examples of the emails you are referring to and tell them that you yourself did not type those emails. Ask if they can explain how this may have happened.

As a general security measure it is also good practice

• to use a limited user account for day to day work not an admin account

• to set passwords up to login to your computer
  http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/usercpl_create_password.mspx
• (IIRC at one time by default XP setup an Administration account with a nul default password, an F8 reboot would get you in by just using the return key when the password prompt showed ) P.S. as mentioned method 3 in this article http://www.slideshare.net/passexpert/six-methods-to-crack-windows-admin-password-remove-unknown-windows-admin-password. Rather a serious security hole.

Hello again iamjayakumars,

Just to advise that the possible solutions that you provided above did not work.  :(((( I am still getting spam emails from own email addresses.  :(((

Do you have any other suggestions perhaps?

but not sure what you mean when you say I must not store it on my computer?

I was just thinking that if someone or some software agent is accessing your computer then they also have access to saved passwords if for instance it is webmail and the password is stored on Firefox, or if you store logins and passwords in any other utility.

I have asked my service provider again for help - waiting to hear from them. I don't store passwords in any other utility that I know of? Are passwords stored automatically somewhere on computers?

An obvious thing to do is also make sure you log out of email and do not leave yourself logged in or use the remember me option.

Yes, thank you, I always log out and never use the remember me option

Thank you for your input. I did report this to my service provider and they assured me that no one is accessing my account? I wonder what they meant by that

   possibly that the account has been accessed only from your computer and the same IP Address has been shown
   Maybe just that the mail used your login and password. 

I have asked them to verify the above - thank you.  :)

What are the emails ? do they make sense, are they also sent to others ? and of course is it likely anyone else is using your computer and sending these emails.

The emails make some sort of sense but not much. As far as I know I am the only one receiving them but just to be safe I deleted my Address Book. No one else has access to my computer - I am the only one who uses it.  :((

it is probably worth contacting them again, give a couple of examples of the emails you are referring to and tell them that you yourself did not type those emails. Ask if they can explain how this may have happened.

Done and awaiting their response.  :) Thank you

what is a limited user account? Also, I am now busy adding a password to my computer and making all files private through User Accounts. Would that help do you think?

If your using gmail check this link

Hello iamjayakumars,

I am not using gmail. These emails are from my own domain name?

Contact your server provider and tell him to block the email addresses.

Another option, use forward option from your domain mail to gmail.

Gmail automatically makes use of spam filter, by this way you avoid the spam mails.

Hello iamjayakumars,

Afraid I cannot have the email addresses blocked, they are business related.  :(( Also can't forward to gmail as again, all business related.  :(((

Hi, could you explain how your emails are spammed?

Or

All mails are spammed, which your getting?

I saw your previous post

How your accessing your emails ? outlook/browser

I am receiving emails in my Outlook Express that says they are from me but they are not from me. Most of them are gibberish. This is happening with two of my email addresses. It looks like the emails are from me, the email addresses are my business email addresses but I am not sending those emails, someone else is?  :((

Outlook Express.

I wonder if I should update my Outlook Express - is that possible maybe? Will it help perhaps?
