....... sorry, my mistake.
I didn't look properly to notice that the thread warning came from \AppData\Local\Temp\
After importing my old settings file again it seems that the exclusion for this folder is working again like before - I don't know what I did wrong the 1st time.
Before when I tried to execute the BAT file from my software folder I got a thread warning, not anymore - Eset is excepting my exclusion again.
I'm sorry for the confusion I caused and thanks a lot to all you guys taking the time to look into this .......
