WowApp application considered dangerous after certificate update
« on: September 14, 2017, 01:20:38 PM »
Hello,

I work for wowapp.com, we've developed a messenger called WowApp, which is normally whitelisted for Avast. We've had to update our code-signing certificate and now we are considered a threat. Can you, please, help me understand what the issue is and how it could be fixed ?

Note: I am obviously not comfortable sharing a dev version of our app on an open forum, so i will add a picture and the name of the build that is considered dangerous. If i understand correctly, the file has already been "submitted for interogation", so you should have access to it.

Please let me know if i can help you with more information. Thank you.

Hey Asyn,

We've already attempted to whitelist the build, but after 3 emails (in the span of 3 weeks), we have no answer yet. We also created a ticket "#943920 Avast considers the WowApp application as a virus.", but still, no answer.  For the second link, as i stated above, we were whitelisted before updating the certificate and we have not changed anything to break the Avast Clean Guidelines.

Because of these reasons, i decided to try the forums for a solution.

Regardless, thank you for the help.

According to your screenshot avast doesn't consider the app as malware.
It is just analyzing it.

Hello,
according to the screenshot it looks that the file is not digitally signed or the signature was not verified. Can you share the file to verify it, please?

Hey Milos,

I uploaded the file on your FTP server, following the guidelines from here https://www.avast.com/faq.php?article=AVKB160.

The name of the archive is
andrei.dica@woowteam.com WowApp.7z
pass: virus

It contains all 3 of our builds: a full isntaller for Windows, a boostrapper for Windows and a full installer for Mac

Let me know if i can help with anything else.

Thank you for the help everybody.

Hello.
our dev team made some changes, but to see the correct info in the popup it requires to release a program update. I have classified the certificate to not send such signed samples to DeepScreen so after next VPS update it should not do to DeepScreen and then CyberCapture.
