What is wrong with my cell phone? Virus?

My cell phone has been showing advertisements on my display for a long time, which is really terrifying because Netflix is always stopped. There's always something about Facebook's advertising preferences. I have already switched off the pop-ups (does not work). When I stop Facebook, everything is blocked and I can't tap on it. I desperately need your help!

But I want to keep my cell phone data

Save data Factory setting.

Download Kaspersky or Bitdefender Free and do a full system scan. That sounds like adware, depending on the design, a common virus.
