Hello!
This is a false-positive with Kaspersky’s methods. Due to the community’s diligent reports, we’ve reached out to them directly and the situation should now be resolved. You may need to update your local copy of Kaspersky in order to get latest changes. Alternatively, marking your local game directory as an exclusion could also help immediately restore functionality (after also repairing your game files through Steam if any executables were unintentionally quarantined).
We hope this resolves your issues!
