How to remove apps installed through installer which displays "Your Mac needs to be updated to improve compatibility" from Mac?

What is "Your Mac needs to be updated to improve compatibility"?

"Your Mac needs to be updated to improve compatibility" is a message in a deceptive pop-up window which appears after launching a fake Adobe Flash Player installer. It is designed to trick users into thinking that by entering the password and clicking the "OK" button they will update the operating system. Although, it installs one or multiple potentially unwanted applications (PUAs) instead. Research shows that this fake installer is used to distribute PUAs such as MediaDownloader, MyCouponsmart, Easy Mac Care and promote the searchmine.net address (fake search engine). However, it may be designed to install or promote some other PUAs or fake search engines as well. Either way, deceptive installers should never be used - there are many cases where they are designed to distribute (install) malware.

Your Mac needs to be updated to improve compatibility scam

Both MediaDownloader and MyCouponsmart are classified as adware, software of this type serves advertisements. It is common that by clicking those ads users end up on questionable websites, in some cases they allow those ads to execute scripts that cause unwanted downloads, installations. Usually, installed adware feeds users with banners, coupons, surveys, pop-ups and/or other types of advertisements. It is worthwhile to mention that apps of this type collect various data as well. More often they target IP addresses, entered search queries, addresses of visited pages, geolocations. However, there are adware-type apps that target sensitive information. Easy Mac Care is a PUA which supposed to make computers run faster and more securely. In other words, it is advertised as a system optimization tool. It is common that PUAs of this type generate fake scan results to deceive users into believing that there are various errors or other issues that supposedly can be fixed with a full version that is not free. Simply said, apps like Easy Mac Care often are designed to extract money from unsuspecting users. Therefore, they should not be trusted. Additionally, this fake Adobe Flash Player is designed to promote a fake search engine (the searchmine.net address). As a rule, rogue installers promote fake search engines by changing browser's settings such as address of a default search engine, homepage and new tab. Such search engines often either display misleading results or results generated by some other search engine (e.g., Yahoo, Google). One more important detail about fake installers (in this case an unofficial Adobe Flash Player installer) is that they can be designed to infect computers with some malware, for example, ransomware, some Trojan, or other malicious program.

To sum up, the "Your Mac needs to be updated to improve compatibility" message (pop-up) appears when users launch a fake Adobe Flash Player installer. This installer is designed to distribute PUAs that may cause problems relate to online privacy, browsing safety, or even identity theft. As mentioned in the previous paragraph, such installers can be designed to infect systems with malware that could cause data, financial loss, installation of other malware, and other serious issues. Therefore, unofficial Adobe Flash player installers (or any other installers of this type) should never be used.

How did potentially unwanted applications install on my computer?

In this case PUAs can be unintentionally downloaded and/or installed through a fake installer. Although, it is not the only way to cause it. It is common that users cause unwanted downloads and/or installations by clicking deceptive advertisements or downloading and/or installing programs without checking settings that are available in their setups. Very often PUAs are included in setups as additional offers that can be declined through their "Advanced", "Custom", or other settings. This distribution method is called "bundling". When users leave the aforementioned settings unchanged, they allow for included PUA to be downloaded and/or installed through a setup of a desired program. Ads can lead to unwanted downloads and/or installations by running certain scripts. However, they can run them only if users click those ads.

How to avoid installation of potentially unwanted applications?

It is not safe to download (and/or install) any software through third party downloaders, installers, from unofficial websites, through Peer-to-Peer networks (like torrent clients, eMule), and other channels of this kind. Files and programs should be downloaded only from official pages and through direct links. It is not any less important to always check all settings that are available in download and/or installation setups. It is common that those settings mention offers to download and/or install unwanted software. Furthermore, intrusive ads, especially if they are displayed on dubious websites, should not be trusted (clicked). Such ads often redirect people to untrustworthy websites or cause unwanted downloads, installations. To stop a browser from opening untrustworthy sites and/or showing ads it is required to uninstall all unwanted, unknown or suspicious extensions, plug-ins or add-ons that are installed on it. Also, if there is any software of this kind installed on the operating system, then it should be uninstalled too. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
