Distribution of ProgressHandler

Potentially unwanted programs such as ProgressHandler Mac are distributed via the so-called “bundling” method. Thus, the undesired program is promoted via rogue installation set-ups that do not disclose properly all apps that are to be installed. If you skip selecting the ” Advanced /Custom” settings, ProgressHandler hijacks browsers and modify various settings imperceptibly.

Impact of ProgressHandler Mac Virus

The ProgressHandler also known as Adware.MacOS.ProgressHandler is an unwanted program that is designed to affect Mac operating systems. Its installation tends to happen behind users’ backs. The program is part of a large network of similar threats that all seek to impact the victim’s security and privacy.

It follows the traditional browser infection patterns by modifying the most important settings on the victim software. Usually, the criminals target the most popular ones (Mozilla Firefox, Google Chrome, and Safari).

Basic threats usually alter only the three basic parameters related to the browser behavior at first launch: new tabs page, default search engine and home page. As soon as this is done the victims will be redirected to a hoax home page or a copied version of a popular search engine like Yahoo or Bing.

The use of a complex multi-stage redirect used by the undesired program can lead to malware delivery with viruses, malware, ransomware and etc. This is the reason why these threats must be removed immediately upon infection.

Like other similar PUPs for Mac, the ProgressHandler institutes tracking cookies that monitor and track all user behavior which is reported back to the program operators. This privacy-invasive tactic is used to make profiles of the users, including their preferences and interests which is gathered in a database shared with all other products operated by the company owner. As the ProgressHandler infects the web browsers it can also extract sensitive information such as the following: history, bookmarks, preferences, cookies, account credentials and passwords.

One of the most dangerous aspects of ProgressHandler being active on a Mac is the chance of obtaining administration rights. For the purpose, the app can generate a pop-up that displays the following message “ProgressHandler will damage your computer”. Do not allow the program what it requests. Otherwise, it may let hackers deliver additional malware to steal sensitive data.
