I have searched and read some. not all as I do not read French, about this file in the subject line. I have four (4) copies of this file in the folder 'emupdate' all of the same size, why do I need this many of the same file? They are all for the same needed operation, "RunOnce" but why four (4)? These should not still be on our systems after being used by Avast! for the Emergency Update, if there is a new one in the next EMupdate. We cannot remove the extra files as they require special permission to do this task. I am a home user and my own Admin to maintain this system. Avast! should remove this file after it is run or give us permission to take care of business on our own systems. The file's name is not as shown in the subject line but each different very long RegKey title.
