dllhost.exe and svchost.exe related Malwares


Recommended Posts

My laptop got affected about 20 days ago when I used the free wifi from a hotel, then I had it looked at by Laptop Clinic, installed Malwarebytes, got rid of much of the viruses, I assume, then updated my windows system, installed Chrome for the hope of less glitches. But it appears that it still got some of the viruses yet to be rid of. First of all, my memory and CPU was eaten up by something unknown, which causes the sudden and really noisy spinning of the fan (never had that before), More importantly,somehow the viruses remain in the laptop and keep downloading malwares to my laptop, popping up windows saying flappy bird pc, etc., Several times I run the Malwarebytes and come back as clean but after a while malwares still show again all of a sudden.


From Malwarebytes protection log I found some of the details are:

Malicious Website Protection, IP,, Outbound, C:\Windows\SysWoW64\dllhost.exe

Malicious Website Protection, IP,, 1e90ff.com, Outbound, C:\Windows\SysWoW64\dllhost.exe


By the way, for no reasons at all, a window says "Host Process for Windows Services has stopped working" keeps showing from time to time, I guess it might be virus related (?)

Here is the problem details:

Problem signature:
  Problem Event Name: APPCRASH
  Application Name: svchost.exe
  Application Version: 6.1.7600.16385
  Application Timestamp: 4a5bc3c1

  Fault Module Timestamp: 53f26cbd
  Exception Code: c0000005
  Exception Offset: 0000000000003fdf
  OS Version: 6.1.7601.
  Locale ID: 1033
  Additional Information 1: a543
  Additional Information 2: a543757d90c8c9f795de5710a00a77fd
  Additional Information 3: a01d
  Additional Information 4: a01deda2367e2f1ef7c265b129bdc753
Thanks very much. I hope my information could be helpful to help get rid of the viruses.

Hey, Kevin, 


Thanks a lot for the instruction.


The FRST kept running for about 5 or 6 hours and it always show "fixing in in progress". I did put the FRST and the fixlist.txt in the same location.  But later I found that a fixlog.txt was generated anyway and FRST was then terminated later by another software you asked me to run.

Your system was infected with Poweliks, This is a typical malware that targets the core system of Windows in order to complete its tasks. Trojan.Poweliks was made to execute a series of commands once it gets inside the system. It will gather data like system settings, Windows version, network configuration, and so on. Collected data will be sent to remote attacker for analysis.

When we are sure your system is clean you will definitely have to change all paswords that are used on this system.....


We still need to run an online AV scan to ensure there are no remnants of any infection left on your system that may have been missed. This scan is very thorough and well worth running, it can take several hours please be patient and let it complete:


Run Eset Online Scanner


**Note** You will need to use Internet explorer for this scan - Vista and Windows 7/8 right click on IE shortcut and run as admin.


(To run ESET Online Scanner in a browser other than Internet Explorer, you'll need to download ESET SMART  Installer during the process)


Go to Eset web page http://www.eset.com/us/online-scanner/ to run an online scan from ESET.


Turn off the real time scanner of any existing antivirus program while performing the online scan
click on the Run ESET Online Scanner button
Tick the box next to YES, I accept the Terms of Use.
Click Start
When asked, allow the add/on to be installed
Click Start
Make sure that the option "Remove found threats"  is UNticked
Click on Advanced Settings, ensure the following options are checked:
Scan for potentially unsafe applications
Enable Anti-Stealth Technology
Select "Change" next to Current scan targets A new window will open, select any extra drives, Flash drives etc as required.
Click Scan
wait for the virus definitions to be downloaded
Wait for the scan to finish


When the scan is complete


If no threats were found
put a checkmark in "Uninstall application on close"
close program
report to me that nothing was found


If threats were found


click on "list of threats found"
click on "export to text file" and save it as ESET SCAN and save to the desktop
Click on back
put a checkmark in "Uninstall application on close"
click on finish


close program


Copy and paste the report in next reply.




There appears to be no anti-virus protection installed on your system, that will leave you very prone to infection the same or similar to what has just been remove.


Install Microsoft Security Essentials at your earliest convenience: http://windows.microsoft.com/en-GB/windows/security-essentials-download


post the log from ESET, also let me know if there are any remaining issues or concerns.....

Hey, Kevin,


Many thanks to the advice.


I think I was a bit too optimistic about my laptop. There actually are many threats found from the ESET scanner, which has been running for almost 24 hours and is still in progress. I'll post the log here as soon as it's complete.

Hey, Kevin,


Sorry to bother you again.


I think right now I'm stuck between a rock and a hard place. The ESET scanner has been running for 4 days which is at least 90 hours, yet the progress bar is still at 44% since the 2nd day. So far it has scanned more than 4 million files and found 71 infected. I did turn off all other anti-virus programme but had to use my laptop sometimes for internet. I attach a screenshot for you. Can you give me some advice here?



Many thanks!

If you are using the laptop during the scan it will freeze or lock up, it can also freeze when identifying infections that may/will try to protect themselves...


Stop the eset scan and run the following:


1.Download Malwarebytes Anti-Rootkit from this link:




2. Unzip the File to a convenient location. (Recommend the Desktop)

3. Open the folder where the contents were unzipped to run mbar.exe




4. Double-click on the mbar.exe file, you may receive a User Account Control prompt asking if you are sure you wish to allow the program to run. Please allow the program to run and MBAR will now start to install any necessary drivers that are required for the program to operate correctly. If a rootkit is interfering with the installation of the drivers you will see a message that states that the DDA driver was not installed and that you should reboot your computer to install it. You will see this image:




5. If you receive this message, please click on the Yes button and Malwarebytes Anti-Rootkit will now restart your computer. Once the computer is rebooted and you login, MBAR will automatically start and you will now be at the start screen. (If no Rootkit warning you will go from step 4 to 6.)


6. The following image opens, select Next.




7. The following image opens, select Update




8. When the update completes select Next.




9. In the following window ensure "Targets" are ticked. Then select "Scan"




10. If an infection is found select the "Cleanup Button" to remove threats, Reboot if prompted. Wait while the system shuts down and the cleanup process is performed.




11. Perform another scan with Malwarebytes Anti-Rootkit to verify that no threats remain. If they do, then click "Cleanup Button" once more and repeat the process.

12. If no threats were found you will see the following image, Select Exit:




13. Verify that your system is now running normally, making sure that the following items are functional:


      Internet access
       Windows Update
      Windows Firewall


14.  If there are additional problems with your system, such as any of those listed above or other system issues, then run the 'fixdamage' tool included within Malwarebytes Anti-Rootkit folder.


15. Select "Y" from your Keyboard, tap Enter.


16. The fix will be applied, select any key to Exit.


17. Let me know how your system now responds. Copy and paste the two following logs from the mbar folder:


System - log

Mbar - log   Date and time of scan will also be shown

Hey, Kevin,


Thanks again for your reply.


I think I didn't quite express the matter very well. The ESET scanner didn't freeze or lock up. Well, it did 2 or 3 times but resumed scanning after some time. The scanning is ongoing because the number of files scanned keeps increasing. But the progress bar just never going beyond 44%. However, I still stop it because I don't want to sit in front of my laptop checking on the scanning during Christmas:-)(I'm afraid it might last that long)


I attach the ESET log it generated after exit.


The results from the MBAR scanning are also attached.

Love the screenie.....


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


Or use the following if first link is down:


"Delfix link mirror"


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:


    Activate UAC
    Remove disinfection tools
    Create registry backup
    Purge System Restore
    Reset system settings


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.


Part of the routine will be to create a registry back up with ERUNT,  the back up will be created here:




When all is known to be well with your system you can delete that back up folder if you consider it as not needed...

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




Read the following link to fully understand PC security and best practices, you may find it useful....




If no remaining issues or concerns are we ok to close out...
