How to avoid auto-deleting my app on broken Windows 11?

[pourkascheff]

I have a full-deplux TCP/IP tranceiver application which I want to run it in another computer for testing purposes but Windows defender antispyware keeps deleting it. (Throws a notification first) My Windows 11 is crashed a bit and I temporarily unable to access Windows Settings>defender antispyware built-in tool. How can I tell it is safe. Is there a way like "Run as administrator" in XAML or such? I'm using 54321 as port and already imported System.Network.Sockets.

Let me ask it differently:
Is it normal? How developers deal with it? I mean the port and the goal itself are not harmful.

Following changes were needed to achieve keeping .exe file:

The rest items are toggled off, a third party antivirus is taking care of things.

Notifications and accesses were also set to low through conventional control panel:

A bank has a contractor that needs to come in and do some work inside the bank vault. So they unlock the vault and leave the door wide open indefinitely to ensure that the contractor will have access to it.

That's the equivalent scenario to what you've done.

A much better solution would be to exclude the specific exe file, or the folder where this exe file resides, from being scanned.

Also, this thread has nothing to do with VB.NET. There's nothing unique about this scenario playing out with a VB.NET exe file vs. an exe file generated by any other compiler written in any other language.

The question probably doesn't belong here, but I'm not quite clear on it, yet, or where would be better. This is a .NET application, but is this happening for ANY application you write, or is it just this one? You also seem to be focusing on the TCP activity, and possibly the port. If you were to comment out that stuff (which might be a fair amount), and build the program, it certainly won't run correctly, but will that solve the problem? If so, then you know what the source of the problem is, but if not, then you are looking at the wrong thing.

How is that sir??? As a beginner, "I wrote a program which unable to open on a 2nd console, what should I do" definitely belongs to VB.NET WinForms forum. How to write a program which automatically tells OS that it is safe? Via code? Via certificate files? Via registry files? The user is below ordinary computer-science knowledge to manage system security and/or firewall settings.

*Edit*: There are portable re*source ha*cker tools out there (wish my account not being suspended for naming these LOL) which are free, plug and play and safe (for operating system) don't know how they're written...

The message on Windows 10/11 is as follows:

In "more info" my app publisher is shown as unknown which it is (I can put some text in it as company name but I'm sure it's not the case) also there is a "Run it anyway" button appearing after pressing more info.

Suppose it is on startup applications. Not going to be delightful experience.

then you know what the source of the problem is

Yes it is sir. Commenting ipv4 tcp/ip network communication lines (the whole point of this app) will not causing any problems.

App.Settings and manifest xaml did not change.

I'm not into placing all codes here but here's the form1 class: idea isn't even mine. It belongs to a random french guy in youtube I followed his steps:

    End Sub
End Class

I'm not even happy with the way this app work. Therefore, if there is a better full-duplex multi node simple ipv4 tcp/ip chat transciever app, it is all welcome here... <3

Here's some of its disadvantages:
- Not responding on sever start until it accepts a client.
- Server only accepts one client.

How to write a program which automatically tells OS that it is safe? Via code? Via certificate files? Via registry files?

Think about this for a bit. If this was possible, then wouldn't every piece of malware out there include this "Don't worry, I'm just an innocuous program..." automation?

[pourkascheff]

You're right... I hated myself immediately after reading my own quotation. So you're telling me let the user install your suspicious app. They trusted you after all and bought your product. Let them open it once, Oh, Windows asks them to run it anyways? They proceed... Result are satisfying and hopefully operating system remembers to recognize your executive file as a safe one.

[Shaggy Hiker]

Yeah, that's often the best option. Signing the application might help, but that's prohibitively expensive for lots of people. I have an application used internally that triggers Windows to warn people when they install it. It's a fairly aggressive warning, too, but so what? It's an internal app, all the users know me.

The reason I was thinking this didn't belong here is just that this could be seen as an application deployment issue. Still, I think the .NET aspects of it are the more interesting ones.
