We have discovered that a few anti-malware scanners are detecting two of our unreal engine executables (UnrealBuildTool.exe and IPhonePackager.exe) as malware and are deleting\quarantining it. You may see issues when attempting to use these two tools.
We are actively working with the vendors in question to to fix the false positives and apologize for any inconvenience!
Stay tuned here for updates regarding this issue.
