Ads by Trezaa

What is Trezaa?

Trezaa is adware-type application that falsely claims to enhance the web browsing experience by providing notifications of special deals/discounts on various online stores, enabling comparison shopping, and enabling other similar functionality. These features may seem legitimate, however, this application is categorized as a potentially unwanted program (PUP).

After successful infiltration on systems without users’ consent, Trezaa collects information relating to web browsing activity and generates intrusive online advertisements.

Trezaa employs a 'virtual layer' to generate various intrusive advertisements. Most of these ads (pop-ups, coupons, banners, etc.) conceal visited website content. This significantly diminishes the web browsing experience.

In addition, the displayed advertisements can lead to malicious websites often containing infectious content - clicking them will result in further adware or malware infections. Furthermore, Trezaa continually gathers various personally identifiable information including IP addresses, website URLs visited, pages viewed, search queries, etc.

This information is shared with third parties who often misuse personally identifiable details to generate revenue. Thus, the presence of an information-tracking app such as Trezaa on your system might lead to serious privacy issues or even identity theft. You are strongly advised to uninstall this PUP immediately.

Research shows that Trezaa has similar characteristics to other adware-type programs such as TrailerWatch, Oasis Space and CaptureItPlus.

All adware falsely claims to improve the web browsing experience (merely attempts to trick users to install). The actual purpose of adware is to generate revenue for the developers - none provide the functionality promised to users. These applications are designed only to deliver intrusive online advertisements and collect personally identifiable information.

How did Trezaa install on my computer?

Trezaa is free for anyone to download on its official website. It is also distributed using a deceptive software marketing method called 'bundling'.

Therefore, users often install Trezaa adware inadvertently. Many users do not pay enough attention during the download and installation processes - they rush these procedures and skip virtually all steps. In doing so, they expose their systems to risk of infection, since many PUPs are hidden within the 'Custom' or 'Advanced' download/installation sections.

How to avoid installation of potentially unwanted applications?

To prevent this situation, be attentive during the download and installation processes. Carefully follow each step using the 'Custom/Advanced' settings. In addition, opt-out of all bundled software listed for download or installation - additionally-included programs are mostly dubious.
