These folders seem to be all over. Last one.
Seeing how I’m going to get you to download OTMOVEIT anyway, we’ll use it.
Please download the OTMoveIt http://download.bleepingcomputer.com/oldtimer/OTMoveIt.exe by OldTimer.
Save it to your desktop.
Please double-click OTMoveIt.exe to run it.
Copy the file paths below to the clipboard by highlighting ALL of them and pressing CTRL + C (or, after highlighting, right-click and choose copy):
C:\Documents and Settings\All Users\Application Data\systemerrorfixer
Return to OTMoveIt, right click on the “Paste List of Files/Folders to be moved” window and choose Paste.
Click the red Moveit! button.
Copy everything on the Results window to the clipboard by highlighting ALL of them and pressing CTRL + C (or, after highlighting, right-click and choose copy), and paste it on your next reply with a new Hijack log.
Close OTMoveIt
Just tell me if the folder was successfully removed. 
If a file or folder cannot be moved immediately you may be asked to reboot the machine to finish the move process. If you are asked to reboot the machine choose Yes.
This looks good. I don’t see where, or what could have created that file.
Any more avast detections?
