Users started to report on early December 2022 that the security system installed on their phones reports that Typing Hero contains virus, malware, or trojan.
That is of course a false positive.
After getting more info from users, I tried reporting the false positive finding to Avast team from their Android app Avast Mobile Security.
Unfortunately, they do not respond.
Around 2 days ago, I send another report using the form on their website.
And today, I got the acknowledgement from their support team that it is indeed a false positive.
I have not get their respond why it was flagged as virus/malware/trojan in the first place.
I will update here once they wrote back.
