How to report potential abuse in Aptoide without becoming a member? The Aptoide store is an alternative platform where you can get Android apps.

I found an app on Aptoide store via Google that has a size of 3.3 MB. The same app with the same app-version in F-Droid store has only a size of 1.1 MB. So I assume that this app is infected by malware.

The Aptoide's info about the suspicious app is 


  Xxxx is Unknown
  
  This classification was assigned because: there is not enough information about the application in Aptoide Anti-Malware platform.
  
  
  Scanned with Anti-Virus: Zoner Anti-Virus   Sophos Anti-Virus   AptoideGuard Malware Analyzer

In the Aptoide website belonging to the app, there is a "report abuse" button but this requires a login (which I don't have and don't want to have)

In the stores impressum, I found an email address so I wrote an email to Aptoide store admin. I got an automated email reply that I should use a web form to contact Aptoide with a link to the web form. So I filled in the web form and submitted it.

This was a week ago and since then nothing happened. The suspicious app is still available in the store and I got no email response.

Is there any other channel to Aptoide where I can report potential abuse without becoming a member?
First: Different sizes do not necessarily mean the bigger one is infected with malware. Or rather, that might depend on your definition of malware: F-Droid compile .apk files themselves, and while doing that, often exclude proprietary parts – such as ad modules.

Second: Aptoide has security checks running on their .apk files. You should find a shield in the app description: Green = checked and OK, Yellow = checked and something suspicious found, Red = checked and infection found1. You can also find details on the checks, where e.g. signatures are compared with other markets (usually Google Play).

Third: Different repositories at Aptoide have a different trust-level. For example, the repository named "Apps" is manually curated by Aptoide staff, and hence quite trustable.

Forth: You can contact Aptoide via a form on their website. You'll have to reveal an email address for that, so they can contact you back.

Fifth: For more details, please see How safe is it to use Aptoide?. Especially check this answer from Paulo (co-founder of Aptoide) and my own answer.



1You will never find the red shield, though – that's only visible for staff. At the same time a red shield is attached, the app is made unavailable for the public.
