The affected files are
Qtwebengineprocess.exe & crashpad_handler.exe
typically located in the EVE Launcher directory. Our tech team is working with Avast to determine what the issue is that’s flagging the false negative, and hope to have an answer soon!
In the meantime, you can find a previous version of the launcher here: https://www.eveonline.com/EveLauncher-1952584.exe
