Hi All,

I'm new here. Got an infection on Friday (first one I know of in a few years) and found bleepingcomputer. You folks do some great stuff.

The problem :
pop up windows show up by themselves with adds - this can happen even when I haven't opened explorer. It appears to be time based, but I'm not sure about that. Also, every so often an audio stream comes on (says something like "you have won a $100 gift certificate to Walmart"). Funny thing about the audio is that no window pops up (even in my task bar) when the audio plays.

What I've done :
Read some posts here to get started. It sounded like jazzpolice had a similar issue, and I followed boopme's first set of instructions to run MBAM and collect the logs. It found something and cleaned it. Rebooted. Had another instance, so ran the full scan instead of the quick scan. The second scan found a trojan and removed it. I'll attach the logs below.

Any thoughts on my next steps?

thanks

dave37

Hi dave37,

Looks like a good start. Let's follow up your scans with this procedure:

Lets see if anything is left out there.

Please download ATF Cleaner by Atribune & save it to your desktop.
alternate download link DO NOT use yet.

Please download and install SUPERAntiSpyware Free
  • Double-click SUPERAntiSypware.exe and use the default settings for installation.
  • An icon will be created on your desktop. Double-click that icon to launch the program.
  • 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 and
    unzip into the program's folder.
    )
  • Under the "Configuration and Preferences", 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 others unchecked):
    • Close browsers before scanning.
    • Scan for tracking cookies.
    • Terminate memory threats before quarantining.
  • Click the "Close" button to leave the control center screen and exit the program.
  • Do not run a scan just yet.
Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Double-click ATF-Cleaner.exe to run the program.
  • Under Main "Select Files to Delete" choose:
    Select All.
  • Click the Empty Selected button.
  • If you use Firefox browser click Firefox at the top and choose: Select All
  • Click the Empty Selected button.
    If you would like to keep your saved passwords, please click No at the prompt.
  • If you use Opera browser click Opera at the top and choose: Select All
  • Click the Empty Selected button.
    If you would like to keep your saved passwords, please click No at the prompt.
  • Click Exit on the Main menu to close the program.
Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp"

ATF-Cleaner must be "Run as an Administrator".

Scan with SUPERAntiSpyware as follows:
  • Launch the program and back on the main screen, under "Scan for Harmful Software" click Scan your computer.
  • On the left, make sure you check C:\Fixed Drive.
  • On the right, under "Complete Scan", choose Perform Complete Scan and click "Next".
  • 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 removal information after reboot, launch SUPERAntispyware again.
    • Click Preferences, then click the Statistics/Logs tab.
    • Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
    • If there are several logs, click the current dated log and press View log. A text file will open in your default text editor.
    • Please copy and paste the Scan Log results in your next reply.
  • Click Close to exit the program.

Thanks, rigel. I did what you instructed (took a while to figure out how to get to safe mode because of how my computer is set up). Here is the log file from SUPERAntiSpyWare :

Hi Dave,

Please print out and follow these instructions: "How to use SDFix". <- for Windows 2000/XP ONLY.
When using this tool, you must use the Administrator's account or an account with "Administrative rights"
  • Disconnect from the Internet and temporarily disable your anti-virus, script blocking and any real time protection programs before performing a scan.
  • When done, the SDFix report log will open in notepad and automatically be saved in the SDFix folder as Report.txt.
  • If SDFix is unable to run after rebooting from Safe Mode, run SDFix in either Mode, and type F, then press Enter for it to finish the final stage and produce the report.
  • Please copy and paste the contents of Report.txt in your next reply.
  • Be sure to re-enable you anti-virus and and other security programs before connecting to the Internet.

Yikes - going from bad to worse.

Ran the SDFix and will post log at the bottom. Then went to my gmail account and clicked on the link to take me back to this thread. Got a popup that said "Thanks for installing mirar" and now I have a mirar ribbon at the top of my internet explorer window when I try to access this post. In addition, now my computer can't get to thebleepingcomputer at all. It goes to other websites, but I can't get here (you can tell I'm using a different computer for this post).

Also, my Symantec came up with a couple of new messages :
Downloader Cleaned by deletion ActiveX[1].htm
Downloader Cleaned by deletion Ms08011[1].htm

So, now to the real question - what next?

Thanks,
Dave

Good morning Dave,

It is time for more specialized tools. Those items must be run in the HJT forum. Please open this guide and follow step (9) - Download HijackThis and create a log.

Good luck with the remainder of your cleaning. We have a great HJT team here - you are in good hands! If you have any questions, please let me know.
