Bitdefender Total Security incorrectly detects viruses in Mafia Trilogy, Mafia III Definitive Edition, and the GOG version of Mafia Definitive Edition every time it's installed and launched. Links to the games in the GOG store are below:

https://www.gog.com/en/game/mafia_iii_definitive_edition
Putting the folders in exclusions no longer helps.
