Issue: How to Block Third-Party Cookies?

I keep receiving ads when browsing, which, apparently, are generated according to my web browsing data. Could you please tell me is there a way to stop such activity?

Solved Answer

block third-party cookies

One of the main reasons why people receive an enormous amount of advertisements while browsing is adware infection. In this case, a scan with a professional anti-malware, for example, Reimage and web browser’s reset should help. However, these days people get the ability to access thousands of websites and use millions of services online for free thanks to the advertisements that bring profit to the website masters in exchange for free services. The problem is that these advertisements are usually annoying, disruptive, and often very personal. For example, if the PC user often visits online shopping sites, looks for information about technologies or visits adult content sites, he or she may notice the corresponding pop-ups. That’s because of tracking cookies, i.e. small text files, which are stored on PC’s browsing directory or program data subfolder. Many websites and third-party software are filled with cookies so that their developers could keep track on how people navigate through the site, what content attracts visitors’ attention, how long the visitor stays on the site and so on. Unfortunately, but for some Internet users associate cookies with privacy violation or, more worse, identity theft because they can collect, store, and transfer data like IP address, PC’s location, email address, web browsing history, and similar. Consequently, many opt for disabling and blocking them.
