When you turn on UEFN's Unreal revision, you may encounter a virus detection warning from Windows Defender.

Cross-posting here from the official response on Twitter: " After investigating we’ve learned that urc.exe was being incorrectly flagged and the false positive is corrected in updated versions of Microsoft Defender. You can find info on updating Windows Defender here: https://www.microsoft.com/en-us/wdsi/defenderupdates "
