Windows Logonui.exe error message

Welcome to Major Geeks!

Some of these are most likely not malware problems and as such, I was going to move your thread to the Software Forum. However, you said you were also having DLLs being detected that are not being removed by Ad-Aware (not surprising that it did not remove them) so let's see if you really have malware problems.

Please follow the instructions in the READ & RUN ME FIRST link given futher down and attach the requested logs when you finish these instructions.

• If you have problems where no tools seem to run, please try following the steps given in the below and then continue on no matter what you find. You only need to try the TDSSserv steps if having problems getting scans in the Read & Run Me First. If TDSSserv is not found, just continue on with the READ & RUN ME.

READ & RUN ME FIRST. Malware Removal Guide

• If something does not run, write down the info to explain to us later but keep on going.
• Do not assume that because one step does not work that they all will not.

• After completing the READ & RUN ME and attaching your logs, make sure that you tell us what problems still remain ( if any still do )!

Helpful Notes:

1. If you run into problems trying to run the READ & RUN ME or any of the scans in normal boot mode, you can run the steps in safe boot mode but make sure you tell us what you did later when you post logs. See the below if you do not know how to boot in safe mode:
   
   • Starting your computer in Safe mode
2. If you have problems downloading on the problem PC, download the tools and the manual updates for SUPERAntiSpyware, Malwarebytes and Spybot ( links are given in the READ & RUN ME) onto another PC and then burn to a CD. Then copy them to the problem PC. You will have to skip getting updates if (and only if) your internet connection does not work. Yes you could use a flash drive too but flash drives are writeable and infections can spread to them.
3. If you cannot seem to login to an infected user account, try using a different user account (if you have one) in either normal or safe boot mode and running only SUPERAntiSpyware and Malwarebytes while logged into this other user account. Then reboot and see if you can log into the problem user account. If you can then run SUPERAntiSpyware, Malwarebytes, ComboFix and MGtools on the infected account as requested in the instructions.
4. To avoid additional delay in getting a response, it is strongly advised that after completing the READ & RUN ME you also read this sticky:
   • Don't Bump! It Only Hurts You!!!

Any additional post is a bump which will add more delay. Once you ​

 

You need to attach the requested log from ComboFix. Also you will need to shutdown your antivirus program and run MGtools.exe again since your log is too incomplete to help us. You antivirus program is most likely having false detection issues.

In addition your MBAM log shows you did not update it and you took no action. You must make sure you update and also fix the problems before saving a log. I suggest that you run it again to make sure the items were actually fixed.

You said you formatted drive C. Are you saying you did this after getting the logs? If so, none of your logs are of any use to us anymore and you will have to start over again and attach all new logs. As stated in the READ & RUN ME, you should only be doing what we ask you to do once you start this process.
