Double-check the file yourself on VirusTotal
Play Protect's scan is a good first check, but it's only one engine. If you want a second opinion before opening the file - or you disabled Play Protect - VirusTotal runs the same apk past dozens of antivirus engines at once, for free, with no account needed.
- Open virustotal.com in your phone's browser, before you tap Open or Install on the downloaded file.
- Tap the upload icon (or "Choose file") and select BetOnGame.apk from your Downloads folder.
- Wait for the scan to finish - it checks the file against 60-70 separate antivirus engines and usually takes under a minute.
- Read the ratio shown at the top: 0-2 flags out of 70-odd is normal background noise for any apk that isn't distributed through the Play Store, not a sign of malware.
- A double-digit flag count, or a well-known antivirus name in the flagged list, is the actual signal to stop and not install the file.
