Hello, I have noticed that apk files generated from AI2Offline are being flagged with Wacatac virus on Windows Defender. I do not want to send apk file to anyone due to privacy concerns. I used NoxPlayer and I get threats found notification when installing my apks. This has never happened in the past and I need a solution because this is a big disaster. Even a blank app with no extensions, code, or components triggered the threats alert.

My two AI2Offline versions were downloaded in August 2021 and April 2022.

Both versions suffer the same issue. Along with one app built with a version of AI2Offline from March 2021.

Do you get the same virus warning if you build with real App Inventor ? If not, this is not an MIT App Inventor issue, you will need to raise this with the developers of AI2Offline.

The virus you mention appears to affect Microsoft Windows ?

I have not tried that yet because I stopped using the real AppInventor for privacy. I will try to build an apk later. And yes this appears to affect Windows 10 21H1. I have not received this since last month when I updated some of my apps and ran them in Nox (the most recent time I worked in AI2Offline)

I built a blank app using real App Inventor and got no false positive.

I still get false positive even on latest version.

I decompiled one of my apps using JADX earlier this year and found references to my username (Windows) to the AppData folder in the apk. I encountered similar issues with developing an AutoHotKey app. Could that be causing it?

here is an example:

moduleMethod7.setProperty("source-location", "C:\\Users\\USER\\AppData\\Local\\Temp\\runtime1994034240844986443.scm:1572");

I just contacted Ai2Offline on SourceForge.

I'm not risking piracy of my apps unless that public link generation becomes its own option like it did in the past. I wish that save to apk option came back.

My business will be downloading these apps. I don't want them to think there is a virus (even a false positive).

I have also reported this to Microsoft because this is a big disaster for me and possibly anyone who uses AI2Offline.

I was wrong, now the APK I exported from real App Inventor now triggers Defender (same Wacatac false positive), and Microsoft said they couldn't reproduce any detection!!!

We cannot reproduce any detection on the file. If the detection is still observed, follow the steps below to capture support log files from the system reporting detection.

now what?
