    Good :)

    Create new restore point before proceeding with the next step....

    - Vista: http://www.howtogeek.com/howto/wind...tore-point-for-windows-vistas-system-restore/
    - XP: http://support.microsoft.com/kb/948247

    ===============================

    Please download ComboFix from Here, Here or Here to your Desktop.

    **Note: In the event you already have Combofix, this is a new version that I need you to download. It is important that it is saved directly to your desktop**
    • Never rename Combofix unless instructed.
    • Close any open browsers.
    • Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.
    • Very Important! Temporarily disable your anti-virus, script blocking and any anti-malware real-time protection before performing a scan. They can interfere with ComboFix or remove some of its embedded files which may cause "unpredictable results".
    • Click on this link to see a list of programs that should be disabled. The list is not all inclusive. If yours is not listed and you don't know how to disable it, please ask.
    • Close any open browsers.
    • WARNING: Combofix will disconnect your machine from the Internet as soon as it starts
    • Please do not attempt to re-connect your machine back to the Internet until Combofix has completely finished.
    • If there is no internet connection after running Combofix, then restart your computer to restore back your connection.
      If the connection is not there use restore point you created prior to running Combofix.
    • Double click on combofix.exe & follow the prompts.

    • NOTE1. If Combofix asks you to install Recovery Console, please allow it.
      NOTE 2. If Combofix asks you to update the program, always do so.
    • When finished, it will produce a report for you.
    • Please post the "C:\ComboFix.txt"
    **Note 1: Do not mouseclick combofix's window while it's running. That may cause it to stall
    **Note 2 for AVG and CA Internet Security (Total Defense Internet Security) users: ComboFix will not run until AVG/CA Internet Security is uninstalled as a protective measure against the anti-virus. This is because AVG/CA Internet Security "falsely" detects ComboFix (or its embedded files) as a threat and may remove them resulting in the tool not working correctly which in turn can cause "unpredictable results". Since AVG/CA Internet Security cannot be effectively disabled before running ComboFix, the author recommends you to uninstall AVG/CA Internet Security first.
    Use AppRemover to uninstall it: http://www.appremover.com/
    We can reinstall it when we're done with CF.
    **Note 3: If you receive an error "Illegal operation attempted on a registery key that has been marked for deletion", restart computer to fix the issue.
    **Note 4: Some infections may take some significant time to be cured. As long as your computer clock is running Combofix is still working. Be patient.


    Make sure, you re-enable your security programs, when you're done with Combofix.

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    NOTE.
    If, for some reason, Combofix refuses to run, try the following...

    Delete Combofix file, download fresh one, but rename combofix.exe to your_name.exe BEFORE saving it to your desktop.
    Do NOT run it yet.
    Download Rkill (courtesy of BleepingComputer.com) to your desktop.
    There are 2 different versions. If one of them won't run then download and try to run the other one.
    You only need to get one of these to run, not all of them. You may get warnings from your antivirus about this tool, ignore them or shutdown your antivirus.

    rKill.exe: http://www.bleepingcomputer.com/download/rkill/dl/10/
    iExplore.exe (renamed rKill.exe): http://www.bleepingcomputer.com/download/rkill/dl/11/

    Restart computer in safe mode

    • Double-click on the Rkill desktop icon to run the tool.
    • If using Vista or Windows 7 right-click on it and choose Run As Administrator.
    • A black DOS box will briefly flash and then disappear. This is normal and indicates the tool ran successfully.
    • If not, delete the file, then download and use the one provided in Link 2.
    • Do not reboot until instructed.
    • If the tool does not run from any of the links provided, please let me know.

    When the scan is done Notepad will open with rKill.txt log.
    NOTE. rKill.txt log will also be present on your desktop.

    Once you've gotten one of them to run, immediately run your_name.exe by double clicking on it.

    IF you had to run rKill post BOTH logs, rKill.txt and Combofix.txt.

    Notes:
    • It was necessary to perform a system restore in order to restore network connectivity.
    • Before restoring, I received a Symantec Endpoint Protection Failure error: "Failure in loading SyLink.dll or one of its dependent dlls. Exiting Symantec Endpoint Protection".
    • Before restoring, I was unable to turn on the Windows Firewall.
    • After restoring, on startup, the windows for The Weather Channel app and an Adobe Flash update notification seemed to be re-positioning themselves left and right by a few pixels without my interaction.
    • I have redacted 368 filenames from the list of "Other Deletions" in the log below, all from c:\users\Tag\AppData\Local\Microsoft\Windows\Temporary Internet Files\.
    • After restoring, the first time I tried to run AIM, it requested permission to make changes on my computer. I denied it. The second time, it did not ask.

    1. Please open Notepad (Start>All Programs>Accessories>Notepad).

    2. Now copy/paste the entire content of the codebox below into the Notepad window:

    Code:
    RegNull::
    [HKEY_USERS\S-1-5-21-419851143-2205390515-4003747433-1001\Software\Microsoft\Windows\CurrentVersion\Shell Extensions\Approved\{A8F62770-6BE0-1832-F360-9D8FEDD0641E}*]
    
    ClearJavaCache::
    

    3. Save the above as CFScript.txt

    4. Close/disable all anti virus and anti malware programs again, so they do not interfere with the running of ComboFix.

    5. Then drag the CFScript.txt into ComboFix.exe as depicted in the animation below. This will start ComboFix again.

    6. After reboot, (in case it asks to reboot), please post the following reports/logs into your next reply:
    • Combofix.txt

    After one reboot, all applications gave me the following error: "Illegal operation attempted on a registry key that has been marked for deletion.", and I was unable to re-enable Symantec Endpoint Protection. After a second reboot, these issues were resolved.

    I assume that my machine is infected since you are having me do so many iterations of scans? I just realized you said "Good" in your second post. Why do you say that?

    Great!

    The computer seems fine. However, it seemed fine before the first scan. That's why I was asking whether you can tell definitively that my machine was infected. Was it?

    Your computer was definitely infected.

    Run OTL
    • Under the Custom Scans/Fixes box at the bottom, paste in the following

      Code:
      :OTL
      SRV:64bit: - File not found [On_Demand | Stopped] -- C:\Program Files\MySQL\MySQL Server 5.1\bin\mysqld -- (MySQL)
      O2:64bit: - BHO: (Expat Shield Class) - {3706EE7C-3CAD-445D-8A43-03EBC3B75908} - C:\Program Files (x86)\Expat Shield\HssIE\ExpatIE_64.dll File not found
      O2 - BHO: (no name) - {02478D38-C3F9-4efb-9B51-7695ECA05670} - No CLSID value found.
      O4 - HKLM..\Run: [WeatherMate] "C:\Program Files (x86)\WeatherMate\WeatherMate.exe" File not found
      O4 - HKU\S-1-5-21-419851143-2205390515-4003747433-1001..\Run: [MobileDocuments] C:\Program Files (x86)\Common Files\Apple\Internet Services\ubd.exe File not found
      
      :Commands
      [purity]
      [emptytemp]
      [emptyjava]
      [emptyflash]
      [Reboot]
      
    • Then click the Run Fix button at the top
    • Let the program run unhindered, reboot the PC when it is done
    • You will get a log that shows the results of the fix. Please post it.

    NOTE. If for any reason OTL stalls (most likely at "killing processes..." step) run the fix from safe mode.

    =============================

    Last scans...

    1. Download Security Check from HERE, and save it to your Desktop.
    • Double-click SecurityCheck.exe
    • 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.

      NOTE SecurityCheck may produce some false warning(s), so leave the results reading to me.

    2. Please download Farbar Service Scanner (FSS) and run it on the computer with the issue.
    • Make sure the following options are checked:
      • Internet Services
      • Windows Firewall
      • System Restore
      • Security Center
      • Windows Update
      • Windows Defender
    • Press "Scan".
    • It will create a log (FSS.txt) in the same directory the tool is run.
    • Please copy and paste the log to your reply.

    3. Download Temp File Cleaner (TFC)
    Alternate download: http://www.itxassociates.com/OT-Tools/TFC.exe
    • Double click on TFC.exe to run the program.
    • Click on Start button to begin cleaning process.
    • TFC will close all running programs, and it may ask you to restart computer.

    4. Please run a free online scan with the ESET Online Scanner

    • Disable your antivirus program
    • Tick the box next to YES, I accept the Terms of Use
    • Click Start
    • Accept any security warnings from your browser.
    • Check Scan archives
    • Click Start
    • ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
    • When the scan completes, click on List of found threats
    • Click on Export to text file , and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.
    • NOTE. If Eset won't find any threats, it won't produce any log.

    Are you able to tell which virus(es) it was infected with?

    The ESET scan was clean.

    Broni Malware Annihilator Posts: 45,175   +242

    You had number of trojans there.

    Update Adobe Reader

    You can download it from http://www.adobe.com/products/acrobat/readstep2.html
    After installing the latest Adobe Reader, uninstall all previous versions (if present).
    Note. If you already have Adobe Photoshop® Album Starter Edition installed or do not wish to have it installed UNcheck the box which says Also Download Adobe Photoshop® Album Starter Edition.

    Alternatively, you can uninstall Adobe Reader (33.5 MB), download and install Foxit PDF Reader(3.5MB) from HERE.
    It's a much smaller file to download and uses a lot less resources than Adobe Reader.
    Note: When installing FoxitReader, make sure to UN-check any pre-checked toolbar, or any other garbage.

    ===============================

    Your computer is clean [​IMG]

    1. We need to reset system restore to prevent your computer from being accidentally reinfected by using some old restore point(s). We'll create fresh, clean restore point, using following OTL script:

    Run OTL

    • Under the Custom Scans/Fixes box at the bottom, paste in the following:

    Code:
    :OTL
    :Commands
    [purity]
    [emptytemp]
    [EMPTYFLASH]
    [emptyjava]
    [CLEARALLRESTOREPOINTS]
    [Reboot]
    • Then click the Run Fix button at the top
    • Let the program run unhindered, reboot the PC when it is done
    • Post resulting log.

    2. Now, we'll remove all tools, we used during our cleaning process

    Clean up with OTL:

    • Double-click OTL.exe to start the program.
    • Close all other programs apart from OTL as this step will require a reboot
    • On the OTL main screen, press the CLEANUP button
    • Say Yes to the prompt and then allow the program to reboot your computer.

    If you still have any tools or logs leftover on your computer you can go ahead and delete those off of your computer now.

    3. Make sure, Windows Updates are current.

    4. If any trojans, rootkits or bootkits were listed among your infection(s), make sure, you change all of your on-line important passwords (bank account(s), secured web sites, etc.) immediately!

    5. Check if your browser plugins are up to date.
    Firefox - https://www.mozilla.org/en-US/plugincheck/
    other browsers: https://browsercheck.qualys.com/ (click on "Launch a quick scan now" link)

    6. Download, and install WOT (Web OF Trust): http://www.mywot.com/. It'll warn you (in most cases) about dangerous web sites.

    7. Run Malwarebytes "Quick scan" once in a while to assure safety of your computer.

    8. Run Temporary File Cleaner (TFC) weekly.

    9. Download and install Secunia Personal Software Inspector (PSI): http://secunia.com/vulnerability_scanning/personal/. The Secunia PSI is a FREE security tool designed to detect vulnerable and out-dated programs and plug-ins which expose your PC to attacks. Run it weekly.

    10. (optional) If you want to keep all your programs up to date, download and install FileHippo Update Checker.
    The Update Checker will scan your computer for installed software, check the versions and then send this information to FileHippo.com to see if there are any newer releases.

    11. (Windows XP only) Run defrag at your convenience.

    12. When installing\updating ANY program, make sure you always select "Custom " installation, so you can UN-check any possible "drive-by-install" (foistware), like toolbars etc., which may try to install along with the legitimate program. Do NOT click "Next" button without looking at any given page.

    13. Read:

    Simple and easy ways to keep your computer safe and secure on the Internet: http://www.bleepingcomputer.com/tutorials/keep-your-computer-safe-online/

    Fantastic! Thanks for your help! I think that I will still avoid using this OS for any important logins, in case of any lurking nasties. BTW, is it possible to know which Trojans they were to assess the scope of what was compromised?

    Some strange observations:
    • Before updating Adobe Reader, there was one session in Chrome where I was not able to load web pages, although other applications (like AIM) requiring network connectivity were still working. Restarting Chrome solved the problem.
    • Secunia PSI hanged several times, requiring several restarts of the application.

    Thanks again :) A few more questions:
    1. How certain can I be that there are no lingering rootkits?
    2. How certain can I be that there are no rootkits that will survive a disk reformatting?
    3. How certain can I be that these viruses have not affected a Linux installation on another HDD in the same system?
  19. Broni

    Broni Malware Annihilator Posts: 45,175   +242

    1. 100%
    2. No rootkit will survive formatting.
    3. Linux won't be affected. Internal drives or external ones?

    2. I'd have to see one for real.
    3. rootkits designed for Windows won't affect Linux and vice versa.
    Internal drives were scanned with our tools.
