Trezaa is adware we recently discovered that displays pop-up ads in your browser window.

Once Trezaa adware has been installed it will create and schedule new tasks to run every time Windows starts. The adware will then use various methods to serve advertisements across affected we browsers. Trezaa ads can often be identified by small text on them that say “Ads by Trezaa.”

Advertisements will arrive on your infected computer system inside affected web browsers, third-party apps, and on Windows Desktop. The ads can affect Google Chrome, Mozilla Firefox, Microsoft Internet Explorer, Apple Safari, and other popular web browsers. Ads can be shown as generic pop-ups, pop-under ads that take up an entire browser window, and in-text advertisements that appear when you hover your mouse over hyperlinked text on a webpage.

Trezaa Distribution Method

Like most adware infections, Trezaa adware primarily bundles with other programs that are downloaded by the user with out without consent. The most common way this happens is by downloading a program or file from a questionable distributor. Downloading items online such as freeware and torrent files will result in potentially unwanted programs infecting the user’s system. Even if a program is well known and trustworthy, downloading it from a malicious site will lead to infection.

If the computer user has recently downloaded a malicious program, Trezaa adware might have automatically downloaded in the background without permission or knowledge of the user. The user might also be tricked into accepting the download under the guise of a program update. Malicious authors often hide the download behind a terms and conditions page, effectively tricking users into downloading adware. In some instances Trezaa may be advertised as an extension to improve the user’s browsing experience in order to encourage a direct download. Regardless of how the system was infected, removal remains relatively unchanged.
