OptiBuy Adware (Mac)

Also Known As: Ads by OptiBuy
Type: Mac Virus
Damage level: Medium

What is OptiBuy?

OptiBuy is a deceptive application that supposedly saves time and money by providing coupons and notifications of special deals/discounts available on various online shops. On initial inspection, OptiBuy may seem legitimate and useful, however, it is categorized as adware and a potentially unwanted program (PUP).

There are three main reasons for these negative associations: 1) stealth installation without consent; 2) display of intrusive online advertisements, and; 3) tracking of users' Internet browsing activity.

OptiBuy adware

Following infiltration, OptiBuy generates pop-up, coupon, banner, and other similar ads. To achieve this, OptiBuy employs a "virtual layer" - a tool that enables placement of third party graphical content on any site. Therefore, displayed ads often conceal underlying content of visited websites, thereby significantly diminishing the Internet browsing experience.

In addition, some lead to malicious websites and clicking them risks further adware or malware infections. Furthermore, OptiBuy continually records IP addresses, URLs visited, pages viewed, search queries, and other information that might contain personal details.

OptiBuy's developers share this collected data with third parties (potentially, cyber criminals) who misuse personal details to generate revenue. The presence of a data-tracking app can lead to serious privacy issues or even identity theft. For these reasons, you are strongly advised to uninstall OptiBuy adware immediately.

OptiBuy is identical to Couponizer, HotShoppy, SurfBuyer, and many other potentially unwanted programs. Note that all of these applications offer identical functionality, however, they are useless for regular users. OptiBuy, and these other adware infections, are designed only to generate revenue for the developers.

They deliver intrusive online advertisements and continually record various user-system information. These applications are useless for regular users.

How did OptiBuy install on my computer?

OptiBuy is free for anyone to download on its official website, however, this app is also promoted using a deceptive marketing method called "bundling". Therefore, many users install OptiBuy inadvertently, without their consent. Bundling is stealth installation of third party applications with regular software/apps.

Developers know that users often rush the download/installation processes and skip steps. Therefore, bundled applications are hidden within the "Custom" or "Advanced" settings of the download or installation processes. By skipping these sections, users expose their systems to risk of various infections.

How to avoid installation of potentially unwanted applications?

There are two simple steps you should take to prevent this situation. Firstly, never rush when downloading and installing software. Select the "Custom/Advanced" settings and carefully analyze each step. Secondly, decline offers to download/install additional applications and opt-out of those already included.
