I am new to UE4 and have version 4.7.0 of the engine installed no problems. Tonight I downloaded 4.6.1 so that I can try out UT4, the installation failed saying “a file access error occurred. Please check your running processes” and then my anti virus program came up saying C:\Program files\Epic Games\Launcher\PatchStagin\UE_4.6Production-Windows\Install\Engine\Extra\Android\tadp-2.0r8-windows.exe has been detected as infected. Bitdefender could not clean this item. Your computer is not virus-free. Virus name:gen:Varient.graftor.143365
I turned off Bitdefender and was able to complete the install, can anyone shed any light as to whether this is a genuine virus or just an anomaly?
