Before a new version of vDos is released, vDosSetup (and vDos itself) is submitted to www.virustotal.com and tested using several (at this moment 61) anti-virus programs. Eventual false positives are then reported (submitting vDosSetup) to those anti-virus companies.
But it seems an anti-virus program could still later on mistrust the same vDosSetup it once approved of; Windows Defender (once/twice ?) did.
If your anti-virus program complains about vDosSetup; first make sure your anti-virus program (its virus database) is up-to-date
. Eventually go to www.virustotal.com
, and check vDosSetup (www.vdos.info/vDosSetup.exe) for yourself.
