How to remove apps that open startmostoriginalprogram[.]icu on Mac computers

What is startmostoriginalprogram[.]icu?

startmostoriginalprogram[.]icu encourages visitors to download and install an update for Adobe Flash Player, however, note that this website cannot be trusted - it actually downloads the FPlayer.zip file, which contains FPSetup.dmg, a file that installs a potentially unwanted application (PUA) or even malicious software. There are many websites similar to startmostoriginalprogram[.]icu online. All are used to trick people into installing unwanted software. They contain no updates for Adobe Flash Player or any other legitimate software.

startmostoriginalprogram[.]icu scam

When visited, startmostoriginalprogram[.]icu displays a pop-up window suggesting that there is a new version of Adobe Flash Player available and encourages visitors to download and install it. As mentioned, this deceptive website downloads a ZIP file that contains a fake installer of a new Adobe Flash Player version. Typically, these fake programs install adware, browser hijackers or even malicious software such as ransomware, Trojans, and so on. If installed, adware-type apps display pop-up ads, coupons, banners, surveys and other forms of advertisements. In most cases, these ads lead to untrustworthy websites and sometimes might be designed to execute scripts to download and/or install unwanted applications (potentially malicious programs). Browser hijacking apps usually promote fake search engines by changing browser settings. Both browser hijackers and adware often gather various browsing data (e.g., IP addresses, entered search queries, addresses of visited web pages, geolocations) and sometimes personal information as well. Developers sell the details to third parties (potentially, cyber criminals) who misuse them to generate revenue. Some web pages such as startmostoriginalprogram[.]icu are used to trick visitors into using installers to infect systems with malicious programs designed to encrypt data, proliferate other malware, and so on. In any case, neither startmostoriginalprogram[.]icu nor other websites of this type should be trusted. None have anything do to with the official Adobe Flash Player or its updates.

Other examples of web pages similar to startmostoriginalprogram[.]icu are theultimatesafevideoplayer[.]info, mainsourceofupgrade[.]best and yourfine2upgradesfree[.]best. All offer to update Adobe Flash Player with a fake installer, which actually installs unwanted software. People often arrive at websites of this type inadvertently: they are redirected to them through other untrustworthy sites, deceptive ads, or browsers automatically open them due to installed PUAs.

How did potentially unwanted applications install on my computer?

Most people download and/or install various unwanted apps (PUAs) through deceptive advertisements (if clicked, these execute scripts designed to download and install PUAs) or via the download/installation set-ups of other software. Developers often distribute unwanted apps using a deceptive marketing method called "bundling" - they include PUAs into the set-ups of other (usually free) programs. Typically, offers to download and/or install additionally-included apps are placed in "Custom", "Advanced" and similar settings of the download and installation set-ups. People who leave these settings unchanged inadvertently allow included PUAs to be downloaded and/or installed.

How to avoid installation of potentially unwanted applications

The safest way to download files and programs is using official websites and direct download links. Some examples of the download/installation tools, sources that should NOT be trusted are unofficial websites, third party downloaders, installers, and Peer-to-Peer networks such as torrent clients, eMule, etc. Check each download or installation setup for settings such as "Advanced", "Custom", "Manual", etc. and dismiss any offers to download or install unwanted software before completing the process. Do not click intrusive ads, especially if displayed on dubious pages. They can open untrustworthy websites or cause unwanted downloads/installations. Dubious ads might also appear on legitimate web pages. If you believe that a PUA is already installed, remove all unwanted extensions, add-ons, and plug-ins from the browser, and programs of this kind from 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.
