I am able to access the internet most of the time, but it is very slow and none of the graphics/images are loading.

Thank you for your help.

Hello.

  • Open HijackThis
  • Choose "Do a system scan only"
  • Check the boxes in front of these lines:


    R3 - Default URLSearchHook is missing
    O2 - BHO: C:\WINDOWS\system32\nhser43uhjnefr.dll - {C2BA40A2-74F3-42BD-F434-2604812C8954} - C:\WINDOWS\system32\nhser43uhjnefr.dll

  • Press "Fix Checked"
  • Close Hijack This.

I suggest you copy these instructions into a notepad file, because we need to use safe mode and you won't have internet access to read from here.

Download SDFix and save it to your Desktop.

Double click SDFix.exe and it will extract the files to %systemdrive%
(Drive that contains the Windows Directory, typically C:\SDFix)

Please then reboot your computer in Safe Mode by doing the following :

  • Restart your computer
  • After hearing your computer beep once during startup, but before the Windows icon appears, tap the F8 key continually;
  • Instead of Windows loading as normal, the Advanced Options Menu should appear;
  • Select the first option, to run Windows in Safe Mode, then press Enter.
  • Choose your usual account.

  • Open the extracted SDFix folder and double click RunThis.bat to start the script.
  • Type Y to begin the cleanup process.
  • It will remove any Trojan Services and Registry Entries that it finds then prompt you to press any key to Reboot.
  • Press any Key and it will restart the PC.
  • When the PC restarts the Fixtool will run again and complete the removal process then display Finished, press any key to end the script and load your desktop icons.
  • Once the desktop icons load the SDFix report will open on screen and also save into the SDFix folder as Report.txt
    (Report.txt will also be copied to Clipboard ready for posting back on the forum).
  • Finally paste the contents of the Report.txt back on the forum with a new HijackThis log

Thank you for your response.

I was able to follow the instructions to:

Download SDFix and save it to your Desktop.

Double click SDFix.exe and it will extract the files to %systemdrive%
(Drive that contains the Windows Directory, typically C:\SDFix)

When I double-click the SDFix icon a box pop up stating the following:

Open File - Security Warning
The publisher could not be verified. Are you sure you want to run this software?
Name: SDFix.exe
Publisher: Unknown Publisher
Type: Application
From: C:/Documents and Settings\Owner\Desktop

It gives me an option to Run or Cancel. When I press Run the box closes and nothing else happens.

Please advise.

Avira probably doesn't like it.
SDFix works better in SAFE MODE.

Did you run it from safe mode?

descriptionInfected by Win32/cryptor EmptyRe: Infected by Win32/cryptor

I have tried it in safe mode and normal both times and I am getting the same error message both times.

Okay, did you do the Hijack This fix anyway?

Please download and run this tool.

Download Malwarebytes' Anti-Malware from Here

Double Click mbam-setup.exe to install the application.

  • Make sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
  • If an update is found, it will download and install the latest version.
  • Once the program has loaded, select "Perform Quick Scan", then click Scan.
  • The scan may take some time to finish,so please be patient.
  • When the scan is complete, click OK, then Show Results to view the results.
  • Make sure that everything is checked, and click Remove Selected.
  • When disinfection is completed, a log will open in Notepad and you may be prompted to Restart. (See Note)
  • The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
Note:
If MBAM encounters a file that is difficult to remove, you will be presented with 1 of 2 prompts.
Click OK to either and let MBAM proceed with the disinfection process.
If asked to restart the computer, please do so immediately.


Post the contents of the MBAM Log.

Yes, I did the Hijack This fix anyway.

I have now downloaded the Malwarebytes' Anti-Malware, but when I double-click the icon nothing happens, when I right click it a menu open and I have clicked on Scan with Malwarebytes'Anti-Malware, but again nothing happens.

Hello.
Thanks for letting me know, I know what's causing the problem now.

1. Please download The Avenger by Swandog46 to your Desktop
Link: HERE or HERE.

  • Click on Avenger.zip to open the file
  • Extract avenger.exe to your desktop

2. Now, start The Avenger program by clicking on its icon on your desktop.

  • Leave the script box empty.
  • Leave the ticked box "Scan for rootkit" ticked.
  • Then tick "Disable any rootkits found"
  • Now click on the Execute to begin execution of the script.
  • Answer "Yes" twice when prompted.

    The Avenger will automatically do the following:

  • It will Restart your computer.
  • On reboot, it will briefly open a black command window on your desktop, this is normal.
  • After the restart, it creates a log file that should open with the results of Avenger’s actions. This log file will be located at C:\avenger.txt
  • The Avenger will also have backed up all the files, etc., that you asked it to delete, and will have zipped them and moved the zip archives to C:\avenger\backup.zip.
3. Please copy/paste the content of c:\avenger.txt into your reply.

Hello.
The rootkit is disabled, now we just have to delete it.
Once it's deleted, MBAM/SDFix will work. Smile...

2. Copy all the text contained in the code box below to your Clipboard by highlighting it and pressing (Ctrl+C):


Drivers to delete:
uacd.sys

Files to delete:
C:\WINDOWS\system32\drivers\UACjwomdnmn.sys


Note: the above code was created specifically for this user. If you are not this user, do NOT follow these directions as they could damage the workings of your system.


3. Now, start The Avenger program by clicking on its icon on your desktop.

  • Under "Input script here:", paste in the script from the quote box above.
  • Leave the ticked box "Scan for rootkit" ticked.
  • Then tick "Disable any rootkits found"
  • Now click on the Execute to begin execution of the script.
  • Answer "Yes" twice when prompted.

    The Avenger will automatically do the following:

Sorry, I don't have an icon for Avenger Sad tearing. I did see it under My Computer and under the C: drive, but I don't know how to open it from there.

The report file you mean?

C:\avenger.txt?

It's just a text file, double click it to open it.

No, I could not even get that far. I am having problems with the first step:



"Now start The Avenger program by clicking on its icon on your desktop"

Hello.
Did you run avenger from your Desktop last time?

"Now start The Avenger program by clicking on its icon on your desktop"

This just means open the program like you did before.
