Flagged as Android.Virus.Gray.Mixopteroidea.B.YYTS.UserCompl? What to do
If you are a user
This is a risk warning about the package. First check whether the app comes from the official website or a reputable app store.
If the warning mentions fraud, gambling, adult content or charges, do not install it, and never enter accounts, verification codes or card details in it.
If you already installed it and paid or entered details, uninstall it, check your accounts and charges, and contact your bank or the police if needed.
If you are the developer
Re-scan the APK on VendorGuard to confirm whether the current version is still flagged and under which name.
Compare the vendor’s warning and the tags in the name against your third-party SDKs, packer, sensitive permissions, promotion behavior and content.
After fixing the issue, or if it is a false positive, submit an appeal on that vendor’s developer platform.
Once the appeal is accepted, re-scan from the VendorGuard report page to confirm the detection is gone.
