Assuming that you haven't implemented anything that is considered malware then it is a false positive.

absolutely no
last compiled version was 2020-08-07 and work fine.

Today i have started b4a, open my project and do F5 without any modification.

The problem is highlighted with the OKHTTPUtils2 library even without using any of its contents, only with the reference.

Today 2 from Italy. My Sources are the same as on Friday.
By removing the reference to the library OkHttpUtils2 the Trojan "disappears".
Also a warning from AVG in the phone.

Probably a false positive from Windows 10 Defender. We'll see in the afternoon ...

okhttputils2 is not a problem.
I am using it in nearly every of my apps. Never had such a issue.

The problem ist probably the sh*** Defender as it seems to be a false positive.

Also Defender will slowdown compile, as Android Studio recommend, exclude your working folders from Defender.

I also experienced this problem today. See the attached PNG for the Windows Updates since I last used B4A (without any problems).
Only a few days ago.

Erel,
Me too on classes.dex a couple times.
I let eliminate the Trojans by Defender and when I copy my Apps to a Backup Stick I get the same message on and on.

same issue in win10 traditional chinese version. I just copied a b4a project folder, and the win defender found the classes.dex as a Trojans,
and the project could not be compiled.
