I didn’t see what type of ads or web pages
I use Fire Fox. I set it to clear caches on closing. I remove Blng from search engine list.
MS browsers constantly push ads and dominance. Bling is horrible at it. I disabled it everywhere I could find.
It could be something installed on the pc.
You can also kill ads in Windows 11. You want them off for gaming anyway.
Key Areas to Disable Ads in Windows 11
Start Menu Ads: Navigate to Settings > Personalization > Start and toggle off "Show recommendations for tips, app promotions and more".
General Privacy Ads: Go to Settings > Privacy & security > General. Toggle off all options, including "Show me suggested content in the Settings app" and those related to the advertising ID.
Lock Screen Ads: Go to Settings > Personalization > Lock screen and set "Lock screen status" to "None".
Taskbar Tips: Go to Settings > Personalization > Taskbar and toggle off "Get tips, tricks, and suggestions as you use Windows".
File Explorer Ads: Open File Explorer, click the three-dot menu, select Options, go to the View tab, and uncheck "Show sync provider notifications".
