1. Install and run a reputable anti-malware program. Malwarebytes is a good option for removing adware.
2. Reset your browser settings to their default values. This will remove any unwanted extensions or plugins that may be causing the pop-ups. Look for the "Reset settings" option in your browser's settings menu.
3. Delete any suspicious browser extensions or plugins. Go to your browser's extensions or plugins settings and remove anything that you don't recognize or that is known to cause adware.
4. Clear your browser's cache and cøøkíés. This will remove any stored data that may be causing the pop-ups.
5. Be cautious of downloading and installing software from unfamiliar sources. Only download software from trusted websites and always read the terms and conditions before installing.
I hope these steps help you get rid of the pop-ups! Let me know if you have any other questions.
