Hi,
when emule (any version) is finishing the file, then avast is doing the antiviral check and if it finds a virus, then it pops up a window to ignore/etc… but sometimes it happens that the file is still opened so it cannot access it and delete the virus infected file but as the file is opened also by avast, the emule cannot finish it properly so the whole thing gridlocks itself and the only solution is to restart a computer as by then you cannot get rid of the avast pop-up window and avast cannot access the original file even if you kill the emule process so
1/ either the avast cannot recognize if the file it wants to ignore still exists (after the emule process was killed) or
2/ it can open the file while emule is still finishing it…
you should do something about that as turning avast off when using emule is not very user-friendly
