If I download a ISO or Exe file in Win 8.1 with Avast, surely the MD5 hash file is wrong.
This happens with many Linux ISO images, Windows ISO from MS Technet or a simple PAF file from PortableApps.com and this happens with a direct download, using a torrent file or a download manager.
Instead, if I download the same file directly from a Linux partition I haven't errors.
Is it possible that it is Avast to damage the files?
Thanks in advance.
