Hi there!
FiveM (
https://fivem.net) is a modification for Grand Theft Auto V enabling you to play multiplayer on customized dedicated servers. This project is open source (
https://github.com/citizenfx/fivem). Avast has been has having lots of false positives on FiveM's .exe files and urls, including but not limited to FiveM.exe, FiveM_DumpServer, CitizenFX.exe.new, and urls mirrors.fivem.net / runtime.fivem.net.
Please fix this issue, as hundreds of players are currently having troubles caused by Avast blocking everything related to FiveM for some reason
