Remove Overbright (Mac Adware)

Another addition to the family of unwanted programs that occupies the homepage is Overbright. It is endorsed as a browser extension that allows Mac users to obtain accurate search results. It may appear as a useful tool, but not every web user is compassionate enough to have it on their browser. To some, Overbright is not essential, and therefore, having it in the browser is just purely displeasure. The problem is that Overbright can be installed on random computers through third-party programs and freeware bundles. This means that some Mac users never have the intention to load this extension.

Is Overbright a computer virus?

Due to the unforeseen appearance of Overbright, some people think that the computer is under virus attack. Technically speaking, adware such as this threat is not classified as a virus because it is not literally contagious. Unlike viruses, Overbright never affects any files on the computer. The adware does not spread to other computers on its own, which is what most viruses do. Furthermore, we can concur that Overbright is just a remake of older adware like OpticalUpdater, Hatchway, and ProduceSelect.

Overbright was made to inflict unsolicited changes on internet applications like Google Chrome, Mozilla, or Safari browsers. The objective is to dominate the default search engine and start-up pages. For whatever purpose, the makers of Overbright are anticipating collecting online information and browsing data from users. In addition, the creators of this adware need to generate online profit through the display of advertisements on search result pages as well as a modified homepage.

Ways to stay away from Overbright adware

  1. Use Official App Stores: Obtain software exclusively from official sources, such as the Mac App Store. Apps on these platforms are generally vetted for security, minimizing the risk of adware.
  2. Avoid Third-Party Websites: Refrain from downloading software from unofficial or third-party websites. These sources may offer compromised versions of applications that could include Overbright adware.
  3. Read Reviews and Ratings: Before downloading an application, check reviews and ratings from reputable sources. Positive feedback from other users can indicate a safe and reliable application, while negative reviews may highlight potential adware issues.
  4. Be Skeptical of Unsolicited Links: Avoid clicking on links in unsolicited emails, messages, or pop-ups claiming to offer free software or system optimizations. These are common tactics used by Overbright adware distributors. Verify the legitimacy of such messages before taking any action.
