I have a Samsung galaxy A tablet and in January my tablet was in infected with the FBI warning virus. I ve been looking online for any information on how to clear this virus out and I can't find anything. I ve downloaded malware apps and anti virus apps and they don't detect anything. I ve tried the safe mode and hard reset and nothing works. I don't know which application is the culprit as I think I waited too long to remove the app. Is this a lost cause or can it be fixed? Please help
