The most effective way to resolve this is to "Reset" the browser. Every major browser (Chrome, Firefox, Edge, Safari) offers a reset option in the settings menu. This action returns the browser to its factory default state, disabling all extensions, clearing temporary data (cookies and cache), and resetting the homepage. It is a slightly inconvenient step, as it requires re-logging into websites, but it is the most reliable method for purging persistent hijack scripts.
If the pop-ups persist despite uninstalling programs and scanning for malware, the browser settings themselves may have been hijacked. Browser hijackers often change the homepage, the default search engine, and the "New Tab" page to redirect users to malicious sites. how to get rid of scam pop ups
