Title: False Positive Detected by Avast Antivirus on Android
Post by: wetter.com on May 23, 2022, 07:15:02 PM
A user reported that avast is detecting a virus in our App. This has to be a false positive, the App works well on millions of devices. I tried reporting via the false positive form, but it appears to be broken.

Play Store link: https://play.google.com/store/apps/details?id=com.wetter.androidclient
Reported issue: Android.Cynos.GEN46903

Please let us know why this happens and if possible fix it. Thanks!

Hi Asyn,

I tried, but the form is broken:

Internal Server Error - Write
The server encountered an internal error or misconfiguration and was unable to complete your request.

Thank you for the links. I am not able to join the whitelisting program, since my APK is too big for the upload. I also can't use the FTP server, because for that I need to join the whitelisting program ... which again is blocked.

I saw another thread about a similar problem .. here the response was "we fixed the error". Would that be an option in our case, too?

Test the APK at VT (https://www.virustotal.com) and post the link to the result here.

Same ... that's interesting, the user reported that this happens in Avast, maybe they got their apps confused?
This is the screenshot they sent along: https://imgur.com/a/oNyaKjE

No idea either, I'd suggest to ask the user if it still happens... ;)
