Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Shipped exe -> Avira Antivir virus alert


I got a problem with the recent version of Unreal Engine 4. I created a new 2D Sidescroll Blueprint project, worked for ~3h on this project and wanted to shipp hit for testing. while packing Avira Antivir popped up with the message that "TR/Dropper.Gen8" was found in the game exe file that is located in the Intermediate folder. Antivir blocked this file, copying failed and so packing also.

This occured on a PC with a complete clean setup (reinstalled everything ~4 days ago), the PC it self is total clean (check multible times with several anti virus and maleware software.)

I disabled Antivir and was able to pack the game and it's working. Copying the packed files to another PC instantly alerts Antivir with the same message of the game.exe. Scanning the file instead with Avira Antivir and nothing found.

Checked on virus total and only Avira got an alert (1/57). I'm extremly sure this is a false alert. But it occures only in this project, other UE 4.13 projects are shipped without any problems. But this Project is the only one that is set as low poly 3D/2D Game and shipped with Development settings (with .pak). Assets are only some basic shapes I created on this PC with Photoshop and 4 basic sounds which are also included in other projects. So there is no chance a virus can get into the Project.

Creating a new Project and migrating all Assets to it caused the same problems. I'm almost 100% sure this is a false alert but you maybe should look at this. Could be a big problem shipping a real game and some virus software triggers a false alert and all are screaming like hell for nothing :D

Here you can download the exe in a .zip file to check it.

That is typical of antivirus software. What it is seeing is a program trying to escalate it's system privileges. This can indicate a virus unless its a program you trust downloaded from a trusted source. So you need to look into extending the privileges so it doesnt keep popping up. It isn't possible for Epic Games to build an installer that automatically gives its program system privileges, that is up to you as the owner or administrator of your system to do.

Then this should happen with all games I'll ship, but It does only for this game/configuration.

I see. Perhaps I misunderstood. I was thinking during the build process. That used to happen a lot to me when I switched from unity to unreal. I am sorry for the misunderstanding.
