We've had a small number of users report to us that their anti-virus software has flagged the Bard's Tale Classic Trilogy Emulated package provided for The Bard's Tale IV backers as malware or a virus.
It goes without saying that these files are not a virus. Rather, this is a false positive result which appears to be caused by the Windows launcher executable that is packaged with the files. This launcher is used to import/export save games between the classic Bard's Tale games, and configure options in the included DOSBox emulator. The launcher file isn't required to play the games, but it does make it easier to set them up and play them.
Only a very small number of anti-virus programs appear to give this result, but if you do receive a warning, we recommend that you whitelist the file and submit it to your anti-virus provider for analysis so that they can resolve the resolve the issue in their virus definitions.
