I created an apk in the Website 2 Apk program. But when I tried to send to a friend, the android's system doesn't gived permission to send. I've tried to send by e-mail, but the Gmail says "Virus Detected". So I scan the apk by antivirus and didn't found nothing. But when I send the apk to VirusTotal, the Cyren detected AndroidOS/Trojan.UDGQ-4. Well, I need explanation about this.
