This morning I clicked on a link on a news website which took me to a rumble video that I wanted to watch. A very short time after getting on rumble my phone seemed to go crazy. Windows were popping up, including my Bitdefender Free AV. I couldn't close any of the windows. I got desperate and tried to restart the phone but the restart button would not stay on long enough for me to click on it. This went on for several minutes when it finally stopped. I was then able to restart the phone. When the phone had restarted I noticed that it had Airplane Mode enabled. I turned off Airplane Mode and the phone seems to be working normally now. I ran a scan with Bitdefender Free and nothing showed up. I decided to start the Trial of Bitdefender Paid Version. I then ran a scan with the Bitdefender Paid Version and nothing was detected. The Bitdefender Paid Version scan results did show something about my email address being compromised (or something like that) three (3) times. I am not sure if this occurred today or was something from the past. What would you do as a next step? Thanks in Advance.
Off the top of my head I would change all my passwords straight away. You could always have a check on your email here for dates and sites where you were pwned https://haveibeenpwned.com
Ghost touch was the first thing I thought of. And even if it wasn't, restarting the phone should fix it. Android has Verified Boot: https://source.android.com/docs/security/verifiedboot
