UltraADSBlockSearch is an annoying PUP (Potentially Unwanted Program) that users are unlikely to download and install intentionally. These intrusive applications are typically spread via questionable tactics, such as being included in suspicious software bundles or pretending to be an installer for a different, legitimate program.

The functionality of UltraADSBlockSearch is multifaceted. The application will take over the installed browsers and proceed to modify several important settings. More specifically, it will set the homepage, new tab page, and the default search engine to now open a promoted Web address. Indeed, users will notice that whenever they launch the browser, open a new tab, or conduct a search via the URL bar, a redirect to an unfamiliar website - ultraadsblocksearch.com, will always be triggered. UltraADSBlockSearch also will establish persistence mechanisms on the device and prevent users from making further changes to the browser's settings.

As for the ultraadsblocksearch.com address, it is classified as belonging to a fake search engine. This means that ultraadsblocksearch.com lacks the most fundamental characteristic of a search engine - the ability to scour the Internet and present users with relevant results on its own. Instead, users will be presented with a list of results taken from other sources. Cybersecurity experts have observed the site showing results from the legitimate Yahoo engine. However, in other cases, users were delivered results from nearbyme.io, a dubious search engine.

Furthermore, the UltraADSBlockSearch PUP also may display data-tracking capabilities. Browser hijackers and other PUPs are often equipped with the necessary functionality to spy on the browsing activities carried out on the system. Some are even capable of collecting various device details (IP address, geolocation, device type, browser type and more) or harvesting sensitive data that has been saved into the affected browsers, such as the user's account credentials, banking information or payment details.
