Hi there

I have a bit of an issue but not sure what the root cause is.

Today, I setup my hotmail account in Outlook today as i thought it would be easier accessing my account from there, so set it up no issues all was working fine. Anyway, couple of hours later, logged in and I've got a load of delivery notification failure emails, some were from old addresses in my address book, some were from addresses i've never seen before. So, something or someone has sent spam to everyone in my address book, plus countless more to people i don't know. Also, whatever has done this has setup a vacation autoresponse with spam as the reply, basically offering cheap electronics, i think this was the content of the emails aswell as they were sent to my sister and neice, so i've seen the emails. I've had this hotmail address for about 9 years and have never had any issues with it until I set it up in outlook.

So, what would be the cause, has someone actually logged in, or do I have some sort of infection. This is the thing thats bugging me as i've ran an Avira scan and malware bytes scan on both my laptop and desktop, both scans didn't reveal anything. For security aswell, i've changed the password on my hotmail account.

What could be the cause, are there any onther measures I can do/run to find the cause. I like to think i'm pretty computer savvy so any advanced things to try and find the cause would be no probs.

Thanks for reading, and hope you can help.

Hello first change your Hotmail account password.

Now run a malware scan with MBam. Run from your regular user account and from normal mode.
Please download Malwarebytes Anti-Malware (v1.32) and save it to your desktop.
alternate download link 1
alternate download link 2
If you have a previous version of MBAM, remove it via Add/Remove Programs and download a fresh copy.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself.
  • Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you after scanning with MBAM. Please temporarily disable such programs or permit them to allow the changes.
