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

What is mainplaceupgradesfree[.]info?

mainplaceupgradesfree[.]info is designed to deceive visitors into using a fake installer for a new Adobe Flash Player version. Typically, websites of this type download installers of various potentially unwanted applications (PUAs). For example, browser hijackers, adware or even malicious programs such as Trojans and ransomware. We strongly advise against downloading anything from mainplaceupgradesfree[.]info or similar web pages.

mainplaceupgradesfree[.]info scam

mainplaceupgradesfree[.]info displays pop-up windows claiming that the installed version of Adobe Flash Player is out of date and encourages users 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 web page downloads a file called "AdobeFlashPlayerInstaller.dmg", which is supposedly designed to install the latest Adobe Flash Player version. In fact, it installs a PUA such as a browser hijacker or adware. Browser hijackers are applications that promote fake search engines by changing certain browser settings. Typically, they also collect information relating to users' browsing activities. The developers misuse the data to generate revenue and/or sell it to third parties (potentially, cyber criminals) who do the same. Many browser hijackers record browsing data and various sensitive information. Adware-type apps can also be designed to operate as information tracking tools too, however, their primary task is to feed users with intrusive ads (coupons, banners, surveys, pop-ups, etc.). Typically, if clicked, these ads open potentially malicious, deceptive and untrustworthy websites, or they execute scripts designed to download/install PUAs that might be malicious. Fake installers/updaters of Adobe Flash Player can infect systems with malicious software such as ransomware, Trojans or other high-risk malware. People who have computers infected with ransomware cannot access or use their data without paying ransoms. If a system is infected with a Trojan, the program usually infects it with other, additional malware. In summary, 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 suggest that Adobe Flash Player is out of date and encourage visitors to update it by downloading and installing a new version. None have anything to do with the official Adobe Flash Player and cannot be trusted. If a browser opens websites such as mainplaceupgradesfree[.]info (or other deceptive, pages) automatically, it is likely that it is forced to do so by a PUA already installed.

How did potentially unwanted applications install on my computer?

Most people download and/or install PUAs inadvertently, through the set-ups of other software or deceptive advertisements. PUAs are commonly included into various download and/or installation set-ups. This distribution method is called "bundling". Generally, offers to download and/or install them can be found in settings such as "Custom", "Advanced", and so on. Unfortunately, people often download and install programs without even checking these settings. Leaving them unchanged can allow included PUAs to be downloaded/installed with regular programs. In other cases, PUAs are downloaded/installed when people click deceptive ads designed to execute certain scripts.

How to avoid installation of potentially unwanted applications

It is not safe to download or install software or files via third party downloaders, Peer-to-Peer networks (e.g., eMule, torrent clients), untrustworthy websites, third party installers, and so on. We recommend that you 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 installations can be avoided by declining offers to download/install additionally-included apps before finishing the process. Do not to click intrusive advertisements, especially those that appear on dubious web pages. Check the list of apps that are installed on the browser for any unwanted extensions, add-ons or plug-ins. Remove all unwanted entries. The same should be applied to 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.
