** BallroomDJ 4 does not have any malware or viruses in it. **
Microsoft's Windows Defender's online anti-virus check will mark novel, small programs as a virus. In BDJ4, this includes the installation extractor, the BDJ4 launcher and the BDJ4 startup helper. Other anti-virus programs will probably have similar issues.
I can submit false positives to Microsoft, and they will fix their database. But many other anti-virus companies do not have a method where false positives can be submitted. And there are far too many anti-virus products for me to do so.
If you have a false positive for BDJ4, and use Windows Defender, let me know, and I can get the false positive cleared. Please include a screenshot from Virus & Threat Protection / Protection History and open the message about the quarantined threat (I need the information from the "Detected:" line).
For other anti-virus products you will need to submit the false positive yourself, or mark BDJ4 as safe on your computer.
To update the anti-virus definitions for Windows Defender, do:
Be sure to exit BallroomDJ 4 before creating a backup or updating the software.
If you are updating BallroomDJ 4 to a new version, be sure to create a backup of your BDJ4 installation. On Windows, simply make a copy of the entire BDJ4 folder.
If the Please install VLC checkbox is selected, an internet connection is required the first time BallroomDJ 4 is installed. The VLC package will be installed via the internet.
If VLC is already installed, no internet connection is required.
Download the Windows installer from sourceforge.
Make sure to exit BDJ4 if it is already started.
Start the installer by double clicking the downloaded file in your Downloads folder.
