How to remove MacOptimizer from Mac?

What is MacOptimizer?

MacOptimizer is a deceptive application identical to Advanced Mac Cleaner, Mac Mechanic, and a number of others. By offering various system optimization-related features, MacOptimizer often tricks users into believing that it is legitimate and useful. In fact, this app is categorized as a potentially unwanted program (PUP). Research shows that, in most cases, MacOptimizer infiltrates systems without permission.

MacOptimizer unwanted application

Following infiltration, MacOptimizer claims to scan the system and display potential errors. Users are encouraged to remove them immediately, however, since MacOptimizer's free version is apparently unable to do so, they are encouraged purchase the full version. Note that the entire list of errors is false - your system is likely to be perfectly safe and optimized. Developers generate revenue by abusing users' trust. MacOptimizer is a useless application and you should never pay for the full version - you are advised to uninstall it immediately. As mentioned above, MacOptimizer usually infiltrates systems without users' consent. There is a high probability that it came together with a number of other PUPs. Research shows that potentially unwanted programs typically do three things: 1) display intrusive advertisements ["Pay Per Click" - PPC - advertising model]; 2) modify web browser options [promoting dubious sites, most of which are fake search engines], and; 3) collect sensitive information [which is later sold to third parties]. These applications deliver no real value for regular users and should be uninstalled.

MacOptimizer shares many similarities with Mac Space Reviver, MyShopcoupon, LiveShoppers, and dozens of other potentially unwanted programs. As with MacOptimizer, these apps also offer certain "useful functions", however, claims to provide them are merely attempts to trick users to install. In fact, all PUPs are designed only to generate revenue for the developers and typically deliver no real value for regular users. PUPs spread intrusive ads, cause unwanted redirects, gather various information, and promote in-app purchases.

How did MacOptimizer install on my computer?

MacOptimizer is free for anyone to download on its official website, however, as with most potentially unwanted programs, it often infiltrates systems without permission. The reasons for this are the careless behavior and poor knowledge of many users. Developers proliferate PUPs by "bundling" and intrusive advertising methods. "Bundling" is essentially stealth installation of third party applications with regular software/apps. Developers do not disclose these installations properly - they hide "bundled apps within "Custom/Advanced" settings (or other sections) of the download/installation processes. Furthermore, many users skip steps and click dubious - yet "tempting" - links/ads. This behavior often leads to inadvertent installation of potentially unwanted programs, such as MacOptimizer.

How to avoid installation of potentially unwanted applications?

The main reasons for computer infections are poor knowledge and careless behavior. The key to safety is caution. Therefore, pay close attention when browsing the Internet and downloading/installing software. Research shows that cyber criminals invest a great deal of time and effort into designing intrusive ads. Therefore, most look legitimate. Once clicked, however, they redirect to gambling, adult dating, pornography, and other dubious sites. If you experience these redirects, immediately eliminate all dubious applications and browser plug-ins. Furthermore, select "Advanced/Custom" settings and closely analyze each step of the download/installation procedures. Decline offers to download/install additional applications and cancel those already included. Note that criminals monetize unofficial downloaders/installers by promoting rogue apps ("bundling" method). Therefore, you are advised to download your apps only from official/certified sources, using direct download links. We also strongly recommend that you use a legitimate anti-virus/anti-spyware suite.
