TopBuyer Ads

What is TopBuyer?

TopBuyer is a potentially unwanted browser extension claiming to save time and money by enabling comparison shopping, coupons, and displaying special deals/discounts available on shopping websites. Although this functionality may seem legitimate and useful, be aware that TopBuyer is categorized as adware or a potentially unwanted program (PUP).

This rogue browser extension employs a deceptive software marketing method called 'bundling' to install on Internet browsers (Internet Explorer, Mozilla Firefox, and Google Chrome) without users' permission.

Bundling allows developers to stealthily distribute their applications together with other software, and for this reason, most users infect their computers with TopBuyer when downloading free software from freeware download websites.

Following successful infiltration, TopBuyer generates various intrusive online advertisements that include coupon, search, in-text, and interstitial ads. There is a high probability that clicking these advertisements will cause high-risk adware or malware infections.

In addition, users' Internet browsing activity is continually monitored, since this PUP records various information that is likely to be personally identifiable.

For example: browser type and versions, cookies, website URLs visited, search queries entered, pages viewed, cookies, IP addresses (to determine users' geo-locations), unique identifier numbers, and other similar software and hardware details. This information tracking may lead to serious privacy issues or identity theft.

TopBuyer is similar to other adware that employs bundling as an installation method. Some examples are: Rad Rater, Malt Mark, Cinemax, and Melodx among many others.

None of these browser extensions are useful to the user - their purpose is to generate revenue by the display of intrusive online ads and sharing collected information with third parties. Therefore, you are strongly advised to eliminate TopBuyer from your Internet browsers.

Research shows that adware such as TopBuyer is mostly distributed via small programs called 'download managers' on freeware download websites (including softonic.com, soft32.com, and download.com).

Download managers are used by these websites as free service monetization tools, since they offer installation of advertised (according to the developers, '100% legitimate') browser plug-ins together with the chosen free software. Thus, careless download and installation of freeware often results in adware or malware infections.

To avoid installation of TopBuyer, or other similar adware, be attentive during download of free software and click 'Decline' if installation of any additional applications is offered.

Furthermore, if you are installing downloaded software, select the 'Advanced' or 'Custom' installation options - this will reveal any bundled applications listed for installation and allow you to decline them. If you have already installed TopBuyer, read the removal instructions provided and remove this adware from your Internet browsers.
