Hi everyone,

My PC started exhibiting bizarre behavior with Windows Explorer hanging and then not being able reboot normally. One time it rebooted, and all I saw was the wallpaper.

The only hint I got as to something unusual going on was an error message on shutdown having to do with AUSUpdateWTitle which I've never heard of before.
After a little Googling, it seemed running Malwarebytes was the thing to do, so I updated it and tried to do a scan. Both a full and quick scan would hang on zipfldr.dll.

After a little more Googling, I was somehow led to reading about the Virtuemonde trojan. I check my registry for MS Juan, but didn't see it.

I have no idea what's going on now. Anyone have any thoughts?

The PC is running XP with the latest SP.

Thanks.

Jane

Let's try this procedure - it includes another run of MBAM after a RKill run.

:inlove: Please download TFC by Old Timer and save it to your desktop.
alternate download link
  • Save any unsaved work. TFC will close ALL open programs including your browser!
  • Double-click on TFC.exe to run it. If you are using Vista, right-click on the file and choose Run As Administrator.
  • Click the Start button to begin the cleaning process and let it run uninterrupted to completion.
  • Important! If TFC prompts you to reboot, please do so immediately. If not prompted, manually reboot the machine anyway to ensure a complete clean.
:flowers: Please download and scan with 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 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 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".

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.
If you have a problem downloading, installing or getting SAS to run, try downloading and using the SUPERAntiSpyware Portable Scanner instead. Save the randomly named file (i.e. SAS_1710895.COM) to a usb drive or CD and transfer to the infected computer. Then double-click on it to launch and scan. The file is randomly named to help keep malware from blocking the scanner.

:thumbsup: Please download RKill by Grinler

  • Before we begin, you should disable your anti-malware softwares you have installed so they do not interfere RKill running as some anti-malware softwares detect RKill as malicious. Please refer to this page if you are not sure how.
  • Download Link #1.
  • Save it to your Desktop.
  • Double click the RKill desktop icon.
    If you are using Vista please right click and run as Admin!
  • A black screen will briefly flash indicating a successful run.
  • If this does not occur please delete that application and download Link #2.
  • Continue process until the tool runs.
  • If the tool does not run from any of the links tell me about it.
:trumpet: Please download Malwarebytes Anti-Malware (v1.44) and save it to your desktop.alternate download link 1

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. Temporarily disable such programs or permit them to allow the changes.
  • 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 definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
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. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.
Note 2:
-- MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes (like Spybot's Teatimer), they may interfere with the fix or alert you after scanning with MBAM. Please disable such programs until disinfection is complete or permit them to allow the changes. To disable these programs, please view this topic: How To Temporarily Disable Your Anti-virus, Firewall And Anti-malware Programs

I'm having a hard time believing this, but after much testing, my boot problems were being caused by the SD card in my card reader. It kept booting without a desktop, and when I tried SafeMode, it wouldn't boot at all. It got stuck right after the drivers I used the SD card in a new outdoor "wildlife camera" I got, and for some reason I couldn't read it on either PC today. (Worked ok yesterday.) I had left it in the card reader of the PC that's giving me trouble. As soon as I removed it, my boot problems went away. I have no clue what that's all about.

Since I'm still very confused about what I was seeing, I'm going to go through all the procedures and will report back. I'm doing the SUPERAntiSpyware scan now.

Thanks very much!

Jane

It could be that your computer is trying to boot to the SD Card... or the drivers for that piece of hardware cannot properly initialize. That can cause issues ...

Let us know about the scans... You will not have to run Rkill. it is a nice checkup :thumbsup:

Hi Rigel,

SAS found nothing but ad tracking stuff, and Malwarebytes found nothing at all without hanging on zipfldr.dll. It's also shutting down and booting right up.

I can only shake my head.

Thanks much for being there.

Jane
