The computer was infected (and still may be) with the Fake AV trojan. I booted into Safe Mode and ran the Eset online scanner, Malwarebytes and Malwarebytes Antiroot kit. Eset found 77 infections, MWB found 338 and there were no rootkits found. I then rebooted into normal mode and ran Spybot 1.6.2, it found another 52 problems. Everything seemed fine until I ran Windows Update and it would not install an update for MSE (KB2902885), The error reported was 0x8004FF80. After doing research on the error, I found a Microsoft Fixit program that would assist in uninstalling MSE. It did not work. I attempted to do the "manual" method of removing MSE and after figuring out that the registry items needed to have the permissions changed to allow for deletion, it seemed to work. 


I ran Windows update again, updated the system and it seemed fine again, albeit without MSE. I attempted to install MSE and now am getting an install error 0x80070643. I just want to install MSE, but think there is still remnants of the trojan out there. 


I am not sure what to do at this time. 


Any help would be appreciated.

Hello, can you post the ESET and MBAm logs.

Then run these

Download TDSSKiller and save it to your desktop.
  • Extract (unzip) its contents to your desktop.
  • Open the TDSSKiller folder and doubleclick on TDSSKiller.exe to run the application, then on Start Scan.
  • If an infected file is detected, the default action will be Cure, click on Continue.
  • If a suspicious file is detected, the default action will be Skip, click on Continue.
  • It may ask you to reboot the computer to complete the process. Click on Reboot Now.
  • If no reboot is require, click on Report. A log file should appear. Please copy and paste the contents of that file here.
  • If a reboot is required, the report can also be found in your root directory (usually C:\ folder) in the form of TDSSKiller_xxxx_log.txt. Please copy and paste the contents of that file here.

    ADW Cleaner

    Please download AdwCleaner by Xplode and save to your Desktop.
  • Double click on AdwCleaner.exe to run the tool
  • Click on the Scan button.
  • AdwCleaner will begin to scan your computer like it did before.
  • After the scan has finished...
    <-insert any special instructions here for what to uncheck OR remove this line if there are none->
  • This time click on the Clean button.
  • Press OK when asked to close all programs and follow the onscreen prompts.
  • Press OK again to allow AdwCleaner to restart the computer and complete the removal process.
  • After rebooting, a logfile report (AdwCleaner[S#].txt) will open automatically (where the largest value of # represents the most recent report).
  • Copy and paste the contents of that logfile in your next reply.
  • A copy of that logfile will also be saved in the C:\AdwCleaner folder.
  • .

    thisisujrt.gif Please download Junkware Removal Tool to your desktop.
  • Shut down your protection software now to avoid potential conflicts.
  • Run the tool by double-clicking it. If you are using Windows Vista, 7, or 8; instead of double-clicking, right-mouse click JRT.exe and select "Run as Administrator".
  • The tool will open and start scanning your system.
  • Please be patient as this can take a while to complete depending on your system's specifications.
  • On completion, a log (JRT.txt) is saved to your desktop and will automatically open.
  • Post the contents of JRT.txt into your next message.
