How to remove apps downloaded from mainplaceupgradesfree[.]info on Mac?

What is mainplaceupgradesfree[.]info?

Mainplaceupgradesfree[.]info website is designed to deceive visitors into using a fake installer of a new Adobe Flash Player version. Typically, websites of this type download installers of various potentially unwanted applications (PUAs), e.g., browser hijackers, adware or even malicious programs like Trojans, ransomware. We strongly recommend not to download anything from mainplaceupgradesfree[.]info or similar web pages.

mainplaceupgradesfree[.]info scam

Mainplaceupgradesfree[.]info displays pop-up windows claiming that installed version of Adobe Flash Player is out of date and encouraging to download (and install) a new version. According to mainplaceupgradesfree[.]info, Adobe Flash Player will not work unless the latest security updates are downloaded and installed. This page is designed to download a file named "AdobeFlashPlayerInstaller.dmg" which supposed to install the newest Adobe Flash Player version. However, it installs some PUA like a browser hijacker or adware, or both. Browser hijackers are applications that promote fake search engines by changing certain browser's settings. Typically, they are designed to collect information related to user's browsing activities as well. Quite often their developers misuse gathered data to generate revenue, and/or they sell it to third parties (potentially cyber criminals) who do the same. It is worth mentioning that there are many browser hijackers that record not only browsing data but various sensitive information too. Adware-type apps can be designed to operate as information tracking tools too. However, more often than not their primary task is to feed users with various intrusive ads (like coupons, banners, surveys, pop-up ads, etc.). Typically, those ads (if clicked) open potentially malicious, deceptive and untrustworthy in other ways websites or execute scripts designed to download and/or install various PUAs that may be malicious. Also, fake installers/updaters of Adobe Flash Player may could be designed to infect a system with malicious software like ransomware, Trojan or other high-risk malware. Typically, people who have their computers infected with ransomware cannot access and use their data without losing money. If a system gets infected with a Trojan, then a program of this type usually infects it with some other, additional malware. To sum up, installation of software downloaded from mainplaceupgradesfree[.]info can lead to financial, data loss, identity theft, problems with privacy, browsing safety, and so on.

Mainplaceupgradesfree[.]info is virtually identical to reliableultimatesafevideoplayer[.]info, operateuberrefinedprogram[.]icu, and many other websites. All of them suggest that Adobe Flash Player is out of date and encourage visitors to update it by downloading and installing a new version. None of them have anything to do with the official Adobe Flash Player and can be trusted. If a browser opens websites like mainplaceupgradesfree[.]info or other deceptive, questionable pages by itself, them it is very likely that it is being forced to do that by some PUA that is already installed on it.

How did potentially unwanted applications install on my computer?

Most people download and/or install PUAs unknowingly, accidentally: through setups of other software or deceptive advertisements. It is very common for various unwanted apps to be included in various download and/or installation setups, this distribution method is called "bundling". As a rule, offers to download and/or install them can be found in setup's settings like "Custom", "Advanced", and so on. Unfortunately, people often download and install programs without even checking those settings. When they leave them unchanged, they allow for included PUAs to be downloaded and/or installed together with a wanted program. In other cases PUAs get downloaded/and or installed when people click deceptive ads designed to execute certain scripts that cause it.

How to avoid installation of potentially unwanted applications?

It is not safe to download or install any software of files via third party downloaders, Peer-to-Peer networks (e.g., eMule, torrent clients), untrustworthy websites, third party installers, and so on. We recommend to download all software only via direct links and from official websites. Furthermore, "Custom", "Advanced" or other similar settings of any download or installation setup should not be left unchecked, unwanted downloads and/or installations can be avoided by declining offers to install (or download) additionally included apps before finishing download or installation process. Additionally, we recommend not to click intrusive advertisements, especially if the ones that appear on shady pages. And finally, it is always a good idea to check the list of apps that are installed on a browser and see if there are any unwanted extensions, add-ons or plug-ins on it. Entries of this kind should be removed. The same should be done with unwanted programs that are installed on the operating system. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
