I have a Samsung android phone. I have a pull down menu to show me who's texting, updates on daily news, the weather, etc. I'm getting notifications from something called tqnq.titan. then it days "tap here to check your device" Then right after that it'll say "your device is hacked" or "we will lock your phone soon. Too much spam" It says Firefox but nothing happens when i tap the notification. What is this and is it spam or a virus? I've been constantly cleaning my phone and running my anti- virus program. It states my phone is clean, but what are these weird notifications I'm getting that I've never gotten before? I'm concerned.
