You can analize as many time you want and you are not going to find DLEAcui.dll again. Do you know why ?... See your OT screenshot.... You sent it to Avast! Virus Chest and that is why.
In your OT your image is from a scan result so the file was detected doing a scan. I told you to look for the scan result that detected it so it should be there unless you erased the result. Also to look for it in the Virus Chest and expand or extend the name of the file. Pondus also gave you directions on how to do so. We also asked you to send the file to VT, and you have not done it either. Polonus is giving you several links where most surely indicates the file is harmless; However, we want to make sure. Also we want to know where the file came from because if it is from a main program, it might not work properly without it and you woul have to restore it.
You have to follow directions in order to get help.
