Antivirus being detected as "suspicious program"

  • Up until a few days ago Twin Saga was running fine. But then it closed whenever I logged into my character with the security alert message "0xE019100B Error: Suspicious program detected. Please close any other programs you have running and restart the game."

    After closing various programs I found that Avast Antivirus was the program it was detecting. I've been using Avast for years without problem. Could this been fixed please?
