I'm pretty sure 99% of this is unimportant, but...
Computer Information: (mostly from the Start Menu -> Computer {right click} -> Properties)
I use Windows 7 Home Premium
Service Pack 1
Model: HP Pavilion dm1 Notebook PC
Processor: AMD E-350 Processor 1.60 GHz
RAM: 8.00 GB (7.60 GB usable)
System type: 64-bit
(I neglected to put anything I thought might possibly be personal, like the Product ID)
Also, I won the computer in a contest a few years ago.


So, anyways, recently, a spambot got a hold of my Yahoo email address, and started sending spam from it, advertising for an online store. I regarded it with mild indifference (after failing to find it with McAfee Security Scan Plus), since most of the accounts receiving spam from it were automated, no-reply email addresses (and so my inbox is often covered in notices telling me the emails could not be sent, as well as one company's automated messages helpfully showing where I can contact them).

However, I just saw that, on Facebook, when I tried to reply to something, it posted my message along with the automated spam message, making it clear to me that I need to get rid of the spambot.

I later realized that it was because Facebook notifies you of new replies via emails, and lets you make a Facebook-reply to the Facebook message by email-replying to the notification emailed to you; so, the spambot just intended to send spam by email, and making a reply on Facebook was entirely unintended on the malware's part.

However, unintended or not, that doesn't change the fact that my Facebook messages will soon be as full of spam as my inbox is of Mailer-Daemon notices.

(also, I registered here with my other, now-personal Gmail account instead, in case such a thing might happen)

Thanks in advance!

Hi,

After performing these scans, enter the results in your next post and also update me on the status of the PC.

Note: You may have to perform some or all of the following in Safe Mode With Networking, depending on if you have internet access while in the normal Windows environment. If you still don't have internet access in Safe Mode With Networking, you will need to download the installers onto a flash drive from a working computer and transfer them to the problem PC.

At the top of your post, click on the Watch Topic Button, select Immediate Notification, and click on Proceed. This will send you an e-mail as soon as I reply to your topic, allowing us to resolve the issue faster.

Also, if you have any of the following programs already installed on your machine, download the latest version along with updates, then run the scan.


Change your email password and Facebook password also.

------------------------------------------------------------------------------------------------------------------------------------------------

Download Security Check by screen317 from here or here.
  • Save it to your Desktop.
  • Double click SecurityCheck.exe and follow the onscreen instructions inside of the black box.
  • A Notepad document should open automatically called checkup.txt; please post the contents of that document.

------------------------------------------------------------------------------------------------------------------------------------------------

Please download and scan with SUPERAntiSpyware Free
  • Double-click SUPERAntiSypware.exe and use the default settings for installation.
    For instructions with screenshots, please refer to the How to use SUPERAntiSpyware to scan and remove malware from your computer Guide.
  • An icon will be created on your desktop. Double-click that icon to launch the program.
  • If it will not start, go to Start > All Prgrams > SUPERAntiSpyware and click on Alternate Start.
  • If asked to update the program definitions, click "Yes". If not, update the definitions before scanning by selecting "Check for Updates". (If you encounter any problems while downloading the updates, manually download them from here. Double-click on the hyperlink for Download Installer and save SASDEFINITIONS.EXE to your desktop. Then double-click on SASDEFINITIONS.EXE to install the definitions.)
  • In the Main Menu, click the Preferences... button.
  • Click the "General and Startup" tab, and under Start-up Options, make sure "Start SUPERAntiSpyware when Windows starts" box is unchecked.
  • Click the "Scanning Control" tab, and under Scanner Options, make sure the following are checked (leave all other options as they are set):
    • Close browsers before scanning.
    • Scan for tracking cookies.
    • Terminate memory threats before quarantining.
  • Click the "Close" button to leave the Control Center screen.
  • Back on the main screen, under "Select Scan Type" check the box for Complete Scan.
  • If your computer is badly infected, be sure to check the box next to Enable Rescue Scan (Highly Infected Systems ONLY).
  • Click the Scan your computer... button.
  • After the scan is complete, a Scan Summary box will appear with potentially harmful items that were detected. Click "OK".
  • Make sure everything has a checkmark next to it and click "Next".
  • A notification will appear that "Quarantine and Removal is Complete". Click "OK" and then click the "Finish" button to return to the main menu.
  • If asked if you want to reboot, click "Yes" and reboot normally.

To retrieve the scan log after reboot, launch SUPERAntiSpyware again.
  • Click the View Scan Logs button at the bottom.
  • This will open the Scanner Logs Window.
  • Click on the log to highlight it and then click on View Selected Log to open it.
  • Copy and paste the scan log results in your next reply.
-- Some types of malware will disable security tools. If SUPERAntiSpyware will not install, please refer to these instructions for using the SUPERAntiSpyware Installer. If SUPERAntiSpyware is already installed but will not run, then follow the instructions for using RUNSAS.EXE to launch the program.

------------------------------------------------------------------------------------------------------------------------------------------------

Please download Malwarebytes Anti-Malware Posted Image and save it to your desktop.
  • Important!! When you save the mbam-setup file, rename it to something random (such as 123abc.exe) before beginning the download.
Malwarebytes 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. Temporarily disable such programs or permit them to allow the changes.

  • Make sure you are connected to the Internet and double-click on the renamed file to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • Malwarebytes 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 and continue.
  • If you cannot update Malwarebytes or use the Internet to download any files to the infected computer, manually update the database by following the instructions in FAQ Section A: 4. Issues.
  • Under the Scanner tab, make sure the "Perform Quick Scan" option is selected.
  • Click on the Scan button.
  • When 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, then click the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked and then 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.
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows the database version and your operating system.
  • Exit Malwarebytes when done.
Note: If Malwarebytes encounters a file that is difficult to remove, you will be asked to reboot your computer so it can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally will prevent Malwarebytes from removing all the malware.

-- Some types of malware will target Malwarebytes and other security tools to keep them from running properly. If that's the case, go to Start > All Programs > Malwarebytes Anti-Malware folder > Tools > click on Malwarebytes Chameleon and follow the onscreen instructions. The Chameleon folder can be accessed by opening the program folder for Malwarebytes Anti-Malware (normally C:\Program Files\Malwarebytes' Anti-Malware or C:\Program Files (x86)\Malwarebytes' Anti-Malware).

------------------------------------------------------------------------------------------------------------------------------------------------

Please download GMER from one of the following locations and save it to your desktop:
  • Main Mirror
    This version will download a randomly named file (Recommended)
  • Zipped Mirror
    This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
  • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
  • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.

    Posted Image
  • GMER will open to the Rootkit/Malware tab and perform an automatic quick scan when first run. (do not use the computer while the scan is in progress)
  • If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
  • Now click the Scan button. If you see a rootkit warning window, click OK.
  • When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
  • Click the Copy button and paste the results into your next reply.
  • Exit GMER and be sure to re-enable your anti-virus, Firewall and any other security programs you had disabled.
-- If you encounter any problems, try running GMER in safe mode.
-- If GMER crashes or keeps resulting in a BSODs, uncheck Devices on the right side before scanning

screen317's Security Check version 0.99.41
Spoiler

I already know how to do the things helpfully highlighted in red (except for defragmenting)

SUPERAntiSpyware
Spoiler



Malwarebytes Anti-Malware
Spoiler

Let's see... I already had (and have used for a different purpose) Malwarebytes Anti-Malware, and I mainly use Firefox, if either of those are possibly of any significance at all.

GMER
Spoiler
About this, I unthinkingly stopped the scan early and started another scan without saving the initial scan results (when I saw that, on the box under the option "Files", D: was not checked, and I tried to correct it), and then the initial scan indicated more registry files(? errors?) than the second scan. Is there a way I might receive the results of the initial scan?


Also, I'm changing my Yahoo (and Facebook) password, but does "Change your email password and Facebook password also" include all other email addresses (as opposed to, only the one that's sent out spam so far), as well?

Thanks for the help, again

There's nothing serious showing up on any of these logs, so I suspect that it's just a problem with someone having your email address and password.

Just change the password for the email that's having the problem and let me know what happens.

I've changed the password for the email address, but, unfortunately, I just received another one of the aforementioned failure notices.

Your email sent more spam even after this?

Well, that's what I'm assuming, since it tells me that I wasn't able to send the following message (followed by your typical spam).

The failure notice itself might help. As everyone knows, if it comes with a bunch of technical stuff, then p(helpful)=0.999

Please follow the instructions in ==>This Guide<== starting at Step 6. If you cannot complete a step, skip it and continue.

Once the proper logs are created, then make a NEW TOPIC and post it ==>HERE<== Please include a description of your computer issues, what you have done to resolve them, and a link to this topic.

If you can produce at least some of the logs, then please create the new topic and explain what happens when you try to create the log(s) that you couldn't get. If you cannot produce any of the logs, then still post the topic and explain that you followed the Prep. Guide, were unable to create the logs, and describe what happens when you try to create the logs.

It would be helpful if you post a note here once you have completed the steps in the guide and have started your topic in malware removal. Good luck and be patient.

If HelpBot replies to your topic, PLEASE follow Step One so it will report your topic to the team members.
