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

    No Infections Detected No Infections Detected

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?

  • I would recommend checking for such things but I know that aptoide is filled with malicious apps and fake apps such that your report won't make a difference. Keep an eye out for outdated, malicious apps and use official channels / curated stores (like Google Play, F-Droid etc). – GiantTree Jun 2 '16 at 11:21

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.

    I have done (4) but got no reaction after a week. (1) the sourcecode at github does not contain proprietary parts (no adds, no google-services). Somthing has been added that is not in the github-s sources. – k3b Jun 3 '16 at 5:21
  • Yeah, 4 has its issues. Sometimes they react very fast, other times one can wait forever. I've reported an issue with their site software half a year ago. No answer yet, issue remains. Pinged Paulo, and they applied a manual fix a day later. Issue was back the day after that ;) So for your case to have effect, afraid you'd need to create an account there and flag the app. – Izzy Jun 3 '16 at 6:16

To answer my own question: Non-member complaint was not possible in my case.

After registering as a new member and then using the "report abuse" link, Aptoide's "copyright infringement-workflow" did the job after one week.


After sending the second form I registered as a new user, loaded the page with the potential malicious app, flagged it as "virus", wrote a comment and pressed the "report abuse" button and send my text.

As a result of "report abuse" activity, I got an automated email

Thanks for your email!

After one additional week, I got an email that the app has been removed from the store.

It was a reply to pushing the "report abuse" link that was made to handle copyright problems with the standard email-text for this use case

Aptoide is deeply committed with the respect of the IPR of Android Developers.

Nevertheless, the suspicious app is not available anymore.
