My mobile phone always pops up websites with bad content when surfing the Internet. What should I do?

You may have downloaded some software, including games. Most of them are bad advertising information, and they didn't go through the mobile phone housekeeper when they were installed, so you were caught. If you didn't download it, someone else may have downloaded it while playing with your mobile phone. Solution: Open the mobile phone housekeeper, find the software that failed the test, and a red-letter dialog box will be displayed, with the permission to prompt whether the software passes or is dangerous. Then you uninstall the software and clean up the residue. So you're finished.
