Well, my first contribution follows here.
I burned a number of CD-Roms and DVD's and found afterwards that they contain this problem. I hope it is a false positive.
Here followes the log and the zipped (7z) WinBraphviz.dll.
If it is a true positive, can I solve this by downloading the iso files, removing the dll and burning again, without a risk ?

Well, the zipped dll is not permitted to upload (sorry)
