360 has uninstalled the joke 100. However, this junk webpage will pop up after opening, and the joke 100 icon will be displayed in the lower right corner of the computer.

Friend, this situation is probably that you have been hit by a malicious plug-in or Trojan horse. I suggest you use 360 security guards to thoroughly kill Trojans in safe mode, then clean up malicious plug-ins, and finally cclean and registry. This should be solved. If it really doesn't work, you can use the 360 system first aid kit to deal with it. Good luck, brother.
