In this digital era, the success of almost every marketing, advertising, and analytics company drives through tracking users across the Internet to identify them and learn their interests to provide targeted ads.
Most of these solutions rely on 3rd-party cookies, a cookie set on a domain other than the one you are browsing, which allows companies including Google and Facebook to fingerprint you in order to track your every move across multiple sites.
However, if you’re using Kaspersky Antivirus, a vulnerability in the security software had exposed a unique identifier associated with you to every website you visited in the past 4 years, which might have allowed those sites and other third-party services to track you across the web even if you have blocked or erased third-party cookies timely.
