If you see “Ads X” ads in Google Search, there is high possibility, that your PC is infected with adware. These ads resemble native Google ads, however they belong to doubtful advertising networks. Usually, such ads, pop-ups and banners are generated by SearchAwesome (in Windows), MacPerformance, MacVX (in MacOS) extensions, however, advertising add-on can be named differently. Extensions can be installed in Safari, Google Chrome, Mozilla Firefox and sometimes in Internet Explorer, Opera and Edge browsers. Links in such ads often lead to potentially unwanted downloads, malicious pages and doubtful online services. We do not recommend you to click on such advertisements, for your safety, privacy and PC security.
