I recommend everybody to install ESET antivirus (free version) and see for themselves..my tivimate is installed from google play and it is paid version..I'm using nvidia shield...ESET warned me about camscanner trojan issue before even google noticed this issue so ESET doesn't give false detection...something is wrong..
Not sure where op downloaded the apk they are scanning but latest Tivimate APK for firestick does not contain a virus according to virustotal, and at virusscan.jotti.org only eset detected a virus - most likely a false positive.
Latest non-google play apk is here:
