Browser hijacker + trojan

Recommended Posts


I have an infection and I’m not quite sure of what it is as so far I've failed to deal with it. I would really appreciate some help.

As far as I’m aware it started on 15/06 and I’m not sure what brought it as I had not downloaded any programs that day. Except for some PDFs and a Firefox update –if it was the latter it genuinely looked like a Firefox update. After rebooting I got the yourtv.lnk hijack. Windows Defender did not detect it, nor has detected any of the associated malware.

I looked up on how to deal with yourtv.lnk following the advise from bleepingcomputer.com and managed to get rid of it, only until I rebooted, then it came back.

While dealing with the above mbam detected the following malware

I also run Rkill. Every time rkill runs it kills the following process dxnbdkv.exe

This file keeps coming back. Supposedly it is located in c:\ProgramData, but I cannot see it there as a hidden file.

I found it on the task manager and disabled it but I guess it will probably come back after rebooting. Note the greyed out file location and properties.

I have also run Adaware which has identified the same process dxnbdkv.exe as Trojan agent BOZV

Once again the location where Adaware found it is c:\ ProgramData\ dxnbdkv \ dxnbdkv.exe, and yet when looking at the files there it does not appear on the list.

It looks to me that although I manage to clean up the system every time I reboot something activates it again.

I have uninstalled Firefox so obviously what comes up as Mozilla is not it.

It’s driving me bonkers and I’m running out of ideas.

Hello Sylvan and welcome to Malwarebytes,

Run the following and post the two produced logs...

Download Farbar Recovery Scan Tool and save it to your desktop.

Note: You need to run the version compatible with your system (32 bit or 64 bit). If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version.

If your security alerts to FRST either, accept the alert or turn your security off to allow FRST to run. It is not malicious or infected in any way...
  • Double-click to run it. When the tool opens click Yes to disclaimer.(Windows 8/10 users will be prompted about Windows SmartScreen protection - click More information and Run.)
  • Make sure Addition.txt is checkmarked under "Optional scans"
  • Press Scan button to run the tool....
  • It will make a log (FRST.txt) in the same directory the tool is run. Please copy and paste it to your reply.
  • The tool will also make a log named (Addition.txt) Please attach that log to your reply.

Thank you,

Morning Kevin

Here are the Farbar logs.



I've also attached mbam logs as of 15/06 and 22/06 -I thought I'd done it on the first post, oops



Also I forgot to mention that yesterday morning my pc got extremely slow at around 9am :o

Adaware has supposedly deleted dxnbdkv.exe, however I haven't rebooted as yet, I don't want to in case it comes back. Was that the clever or dumb thing to do?

Thanks for the logs Gaby,

Continue as follows....

Download attached fixlist.txt file (end of reply) and save it to the Desktop, or the folder you saved FRST into.
NOTE. It's important that both FRST and fixlist.txt are in the same location or the fix will not work.

Run FRST and press the Fix button just once and wait.
The tool will make a log on the Desktop (Fixlog.txt) or the folder it was ran from. Please post it to your reply.

Go here: https://www.zemana.com/Download download and install Zemana Anti-malware. Allow a shortcut to be saved to your Desktop.. The tool will be active with a 15 day trial....

Thanks for the update, run the following to clean up....

To UNinstall Zemana and Sophos use the following:

Download GeekUninstaller from here: http://www.geekuninstaller.com/download (Choose free version) Save Geek.zip to your Desktop. (Visit the Home page at that link for necessary information)

Extract Geek Uninstaller and save to your Desktop. There is no need to install, the executable is portable and can also be run from a USB if required.

Run the tool, the main GUI will populate with installed programs list,

Left click on Program name to highlight that entry.

Select Action from the Menu bar, then Uninstall from there follow the prompts.

If Uninstall fails open the "Action" menu one more time and use "Force Removal" option


Download "Delfix by Xplode" and save it to your desktop.

Or use the following if first link is down:

"Delfix link mirror"

If your security program alerts to Delfix either, accept the alert or turn your security off.

Double Click to start the program. If you are using Vista or higher, please right-click and choose run as administrator

Make Sure the following items are checked:

  • Remove disinfection tools
  • Purge System Restore <--- this will remove all previous and possibly exploited restore points, a new point relative to system status at present will be created.
  • Reset system settings <--- this will reset any system settings back to default that were changed either by us during cleansing or malware/infection

Now click on "Run" and wait patiently until the tool has completed.

The tool will create a log when it has completed. We don't need you to post this.

Any remnant files/logs from tools we have used can be deleted…
