Sup hoes, I'll jump right into it.

Workstation at a clinic is infected with a piece of malware that disables antivirus as soon as it's accessed. So far I've tried to run AVG's scan and MalwareBytes' scan. Running malware bytes once after installing will start the scan and the search is stopped seconds after initializing, program is terminated. At this point then the program can not be opened. Attempting to open mbam.exe delivers error "Windows can not access the specified device, path or file. You may not have the appropriate permissions to access the item." Identical results if repeating this entire process in safe mode.

Installing AVG; AVG Active Anti-Virus (the real-time scan) disables and can not be enabled. An attempt at a scan with AVG results in an immediate conclusion stating no threats were found (nothing scanned). Safe mode is similar, the AVG scan will run for about 15 seconds then just simply close.

The only active process I found out of the ordinary was this entry: "3517402925:3534772270.exe" - 464K. Ending the process does not seem to have any effect; it remains there. It is an active process in Safe Mode as well. Found registry entry in
LOCAL_MACHINE > System > Services > 2d4fa7d1 >
name: imagepath
data: \systemroot\3517402925:3534772270.exe

Also appears in
LOCAL_MACHINE > System > CurrentControlSet > Services > 2d4fa7d1
LOCAL_MACHINE > System > ControlSet003 > Services > 2d4fa7d1

Deleted all these entries and they appear immediately after rebooting of course. I can not find the actual file "3517402925:3534772270.exe" ; A search for "*3534772270.exe" (without quotes) in the entire hard drive provided no results. There are no files in my C:\Windows that resemble this. There are either 1 or 2 files that start with numbers but are not the culprit as far as I can tell. Hidden folders/files are shown, naturally.

No malicious entries in in the Startup list
I didn't see anything malicious in Services but I didn't spend extensive time there.

How do I rid of this nuisance? I'm confident I can take care of this easy so long as I can actually end the process. I'd also say I'm 90% confident the issue with the antivirus programs are coming from this mysteriously titled file.

Thanks, I absolutely love you guys. <3

Hi Putrid, :busy:

I know it looks like a lot, but it's really just a lot of text asking for only 4 scans.

Once you've done these and posted the results in your next post, let me know how the computer is running.

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.

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

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

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.
  • 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.

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

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

Please download Malwarebytes Anti-Malware 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.
    For instructions with screenshots, please refer to this Guide.
  • 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 encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
  • 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.

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

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

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
.

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

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

Remember, after posting the results of these scans, let me know how the computer is running.

I installed and edited the settings of SAS as directed. Booted in safe mode and started a scan, it last several seconds and again was terminated, the program no longer able to boot due to the error "Windows can not access the specified device, path or file. You may not have the appropriate permissions to access the item." whenever attempting to open.


GMER installed with no problems. Before scanning I did check the services and processes, etc. I am unsure of the reasoning but GMER colored the mystery process in red. There was also a service, starting manually, for this mysterious file, also colored in red. I once again I could not kill the process or delete the service; Killing the process yielding no result, and deleting the service provided an error stating simply that it could not be deleted.

I pressed the "Scan" button and it ran for about 30 seconds before being terminated and, like MalwareBytes, ruined the program so that I could no longer open; It now provides error message "Windows can not access the specified device, path or file. You may not have the appropriate permissions to access the item."

Since there were checkboxes for each type of scan I could do, I went down the list one at a time until I found that "Processes" is what will immediately terminate the app and... corrupt it, I guess. I ran another scan without processes checked.

Watching it closely for a painful 1.5 hours, while it was scanning the files, an entry popped up under "ADS" that was the mystery file again at c:\windows\3517402925:3534772270.exe. I right-clicked and saw an option to kill file, but before I was able to select it, the program terminated and became corrupt :( Here is a copy of the log with "Processes" and "Files" unchecked:
