Random .exe file keeps regenerating in each boot


Recommended Posts

First of all, let me say that I've tried to use Malwarebytes to solve the problem. It sure cleaned all of my malware (I was surprised I actually had that many of them before), but not this one.

The file that persistently keeps appearing on my computer is this kind of .exe: http://i.imgur.com/uy49Dk7.png

Everytime I boot the PC the crash report also appears on my computer saying this program has BEX error or something (Sorry I hadn't the chance to screencapped it because it was accidentally closed). All I do to "prevent" this is by deleting the file, but it always sorta find its way to regenerate. And this time the name wouldn't be "qngi.exe". It could be anything stupid like "fewnjwn.exe" or any other random letters. The "product name" also looks like it was randomly generated (and sometimes it's nothing like this one: http://i.imgur.com/v3DjD1l.png)

I am still not pretty sure what causes the file to regenerate in each boot, so I guess you guys could help me with this harmless-yet-still-kinda-upsetting bug. I have attached the frst.txt and addition.txt in this post and let me know if you need any additional info in order to solve this.

STEP 01
RKill is a program that was developed at BleepingComputer.com that attempts to terminate known malware processes so that your normal security software can then run and clean your computer of infections.
When RKill runs, it will kill malware processes and then removes incorrect executable associations and fixes policies
that stop us from using certain tools. When finished it will display a log file that shows the processes that were
terminated while the program was running.

As RKill only terminates a program's running process and does not delete any files, after running it, you should not reboot
your computer as any malware processes that are configured to start automatically will just be started again.
Instead, after running RKill, you should immediately scan your computer using the requested scans I've included.

Please download Rkill by Grinler from one of the links below and save it to your desktop.

Link 1 | Link 2

  • On Windows XP Double-click on the Rkill desktop icon to run the tool.
  • On Windows Vista/Windows 7 or 8, right-click on the Rkill desktop icon and select 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.
  • If it does not work, repeat the process and attempt to use one of the remaining links until the tool runs.
  • If the tool does not run from any of the links provided, please let me know.
  • Do not reboot the computer; you will need to run the application again.

STEP 02
Backup the Registry:
Modifying the Registry can create unforeseen problems, so it's always wise to create a backup before doing so.

  • Please download ERUNT from one of the following links: Link1 | Link2 | Link3
  • ERUNT (Emergency Recovery Utility NT) is a free program that allows you to keep a complete backup of your registry and restore it when needed.
  • Double click on erunt-setup.exe to Install ERUNT by following the prompts.
  • NOTE: Do not choose to allow ERUNT to add an Entry to the Startup folder. Click NO.
  • Start ERUNT either by double-clicking on the desktop icon or choosing to start the program at the end of the setup process.
  • Choose a location for the backup.
    • Note: the default location is C:\Windows\ERDNT which is acceptable.
  • Make sure that at least the first two check boxes are selected.
  • Click on OK
  • Then click on YES to create the folder.
  • Note: if it is necessary to restore the registry, open the backup folder and start ERDNT.exe

STEP 03
Please run a Threat Scan with MBAM. If you're unable to run or complete the scan as shown below, please see the following:
MBAM Clean Removal Process 2x
When reinstalling the program, please try the latest version.

Right click and choose "Run as administrator" to open Malwarebytes Anti-Malware and from the Dashboard please Check for Updates by clicking the Update Now... link
Open up Malwarebytes > Settings > Detection and Protection > Enable Scan for rootkit and Under Non Malware Protection set both PUP and PUM to Treat detections as malware.
Click on the SCAN button and run a Threat Scan with Malwarebytes Anti-Malware by clicking the Scan Now>> button.
Once completed please click on the History > Application Logs and find your scan log and open it and then click on the "copy to clipboard" button and post back the results on your next reply.

There is a PowerShell script running on the computer that is probably a threat. Let me have you do the following, please.

Click on START and type in CMD.EXE and hit the Enter key.

Then type the following exactly or if possible copy / paste to the command prompt box.

 

reg export "HKEY_CURRENT_USER\Software\Classes\gzsSxaUYf"    "%USERPROFILE%\desktop\possible_threat.txt"

 

That should create a file on your desktop named "possible_threat.txt" , please attach that file as an attachment to your next reply.

Thanks

Please download the attached fixlist.txt file and save it to the Desktop.
NOTE. It's important that both files, FRST or FRST64 and fixlist.txt are in the same location or the fix will not work.

NOTICE: This script was written specifically for this user, for use on this particular machine. Running this on another machine may cause damage to your operating system.

Run FRST or FRST64 and press the Fix button just once and wait.
If the tool needs a restart please make sure you let the system restart normally and let the tool complete its run after restart.
The tool will make a log on the Desktop (Fixlog.txt). Please attach or post it to your next reply.

Note: If the tool warned you about an outdated version please download and run the updated version.

fixlist.txt

 

Thanks
