Mezza virus

Mezaa is the name of a shopping assistant service developed by PureDirect, LLC, which is supposed to make web browsing more convenient with the Direct Navigation, Savings/Deals Offers, and Price Compare Widget key features. However, it exhibits characteristics typical of adware[1] programs and falls for the group of Potentially Unwanted Programs (PUPs). Some popular AV engines detect it as Suspicious_GEN.F47V1109 or Artemis!FB9ED40BCDC8, meaning that it's advertising campaigns may be quite aggressive.

Reimage is a reliable security tool that can eliminate Mezaa and related apps with one click. 

Mezaa software has an official website. It's not only non-informative but also lacks a download button. That's a clear sign that the app is malware. Since 2014, it is circulating on the Internet as an “optional download” or various freeware, which do not unpack the package unless the PC's user asks for it. 

Once installed, it changes Windows startup system and starts running MZA.exe, MezaaSvc.exe, and Mezaa.Service.exe process within Task Manager. They are responsible for the execution of the adware, as well as injection of a related extension to the default web browser, be it Chrome, Firefox, Edge or Safari. Right after the installation, people start noticing abnormal web browser's behavior. 

First of all, web browser's load time may be prolonged, so you may be forced to wait for the startup window to open for a minute or two. However, the most prominent sign of the Mezaa virus presence is a continuous attack of ads. Pop-ups, banners, interstitial ads, textual links, full-page ads, etc. may flood your screen disrupting web browsing activities. 

Usually, Mezaa ads contain various offers that are available on its partners' web stores. However, some of the pop-ups may be powered by suspicious third parties that may try to foist useless services or trick people into downloading malware. Therefore, if you see ads saying that your system is infected with a virus or that you have been selected to win valuable prizes, do not fall for clicking on them. Such and similar ads maybe a catch leading to phishing or scam[2] websites. 

In addition to intrusive ads, Mezaa virus aims at collecting users' Search Data. It includes IP address, email address, search queries, most visited websites, and similar browsing-related information. Even though it's not considered as personally identifiable (PI), its disclosure to third parties is not recommended. That's because the number of ads may grow up even more. Besides, they may be improved according to your preferences, thus have more potential to be clicked on. 

Anyway, we encourage you to remove Mezaa from the system. This way, you will clean the system from malware, as well as delete intrusive content from your web browser. The easiest way to get rid of unwanted programs is to run a full scan with a professional anti-virus. Nevertheless, you can perform Mezaa removal manually with the help of a guide given at the end of this article. 

Adware can unravel its ads with the help of freeware

Not all, but many adware-type programs can be downloaded from official websites or sometimes from such reliable sources as Google Play Store. In some of the cases, like in this one, adware has an official website, which does not provide a download button. That's a clear sign that the app you are looking at is a PUP, which is being distributed along with freeware. 

Such unwanted tools are usually hidden under Quick or Basic installation options and marked by default. Consequently, if the PC's owner selects one of these options, he or she unconsciously permit to install the whole software package. 

To prevent the unexpected appearance of such apps, be very careful when installing freeware and shareware on your PC. The easiest way to disclose the bundle and reveal additional downloads is to choose Custom or Advanced installation option. Do not click the Next button for trying to speed up installation because you may easily miss the check mark that allows installation of PUPs.
