Remove MainReady – Mac Adware

By | Posted on April 7, 2020 |

Adware refers to applications that inject intrusive advertisements and pop-up alerts on the computer in order for its authors to generate online profit. Aside from Windows systems, Mac computers are also the target of adware infections. There are plenty of adware applications spreading online. One example of adware that can compromise Mac computers is called MainReady. Developers endorsed MainReady as a useful application for enhancing the browser functions of Mac computers by performing fast searches and delivering precise results. However, just like any other adware like UltraLocator and PlusSpecial, MainReady operates maliciously once installed on the Mac computer.

Though MainReady may seem like a legitimate application, it does not function as to what it claims. Instead of improving the browser functions, MainReady will cause interruptions to the browsing activity of Mac users. The browser will start to exhibit unwanted advertisements in different forms such as fake discount coupons, promotional surveys, commercial ads, or campaign banners. As long as the Mac user is online, adverts will keep showing on the Mac computer screen diminishing the browsing experience of Mac users. But it does not end there; the ads generated by MainReady can cause the browser to redirect into dubious websites. Most of the advertisements coming from adware applications like MainReady are promoting fake software updates or potential scams. Besides, some ads can execute scripts to download and install potentially unwanted applications (PUA). In other words, MainReady can cause additional intrusions of malicious software on the Mac computer.

MainReady

The majority of Mac users do not really install MainReady on their Mac computers intentionally. This happens because MainReady has the ability to infiltrate Mac computers without consent from Mac users. Unauthorized installation is possible through malicious installers that include MainReady along with other software. The installer will not disclose any descriptions of MainReady such as uninstall instructions or its functions. Therefore, Mac users might not know that there is extra software on the installation, which mostly happens to be an unwanted application.
