Something very strange happened today. My galaxy note 1 all of sudden started playing a random music that I am very certain it's not stored in by myself and I have never heard of that song before. I looked up online trying to find an antivirus to scan my phone but apparently most of the articles I read said the antivirus on android are all useless. Does anybody know what happened or what I can do to find the malicious app?
TIA
