How to remove Opera from Mac computers
What is Opera?
Opera is a legitimate web browser, however, research shows that some affiliate marketers generate revenue by promoting it through fake Adobe Flash Player installers and other rogue download/installation set-ups - they use them to trick people into downloading and installing potentially unwanted applications (PUAs) such as browser hijackers and adware. In some cases, they use them to distribute malicious software including ransomware, Trojans, and other malware. Therefore, third party downloaders and installers should not be used to download or install any software.
Many deceptive websites attempt to trick visitors into believing that the installed version of Adobe Flash Player is out of date. They encourage people to use rogue downloaders/installers, which actually download and install unwanted, potentially malicious software. In this case, the downloaded fake Adobe Flash Player installer installed Opera. As mentioned, this is a legitimate web browser, however, if it was downloaded and installed unintentionally, it is likely to have been caused through a rogue download/installation setup promoted through a deceptive website. These websites and download/installation set-ups cannot be trusted, since they are often used to trick people into downloading and installing PUAs or even malicious software. They distribute PUAs such as adware and browser hijackers. Most adware-type apps display advertisements. When clicked, these open dubious websites or cause unwanted downloads and installations. PUAs can record browsing-related information including sensitive, personal details. Browser hijackers also track information. Additionally, they promote the addresses of fake search engines by changing browser settings. Trojans are malicious programs that often cause chain infections by downloading and installing other malware (e.g., ransomware). Ransomware encrypts data and, in most cases, victims cannot decrypt their files without specific tools held only by the cyber criminals who designed the ransomware program. In summary, fake Adobe Flash Player installers and other rogue download/installation set-ups can be the reason behind unintentional installations of legitimate software such as Opera, however, they can also cause infiltration of PUAs and malicious programs - these can cause problems such as identity theft, monetary, data loss, issues relating to browsing safety, privacy, and so on. Therefore, software and files should never be downloaded from unofficial, deceptive websites, or downloaded/installed through rogue set-ups.

Some examples of websites that are designed to promote fake Adobe Flash Player installers include bestevervideoplayernew[.]info, worldofcontenting[.]info and theultimatesafevideoplayers[.]info. Typically, these web pages claim that Adobe Flash Player is out of date and encourages people to install a new version through a rogue setup. If the Opera browser is installed on the operating system but was not downloaded or installed intentionally, a rogue setup is probably responsible. Note that the setup may also have been used to distribute PUAs.
How did potentially unwanted applications install on my computer?
In most cases people download and install potentially unwanted applications (and sometimes legitimate software such as Opera) inadvertently when they are included into the download/installation set-ups of other software. This distribution method is known as 'bundling'. Developers use this method to trick people into downloading and installing unwanted programs together with their required software. In most cases, information about additional downloads and installations can be found in settings such as 'Custom', 'Advanced', and 'Manual', however, many people download and install programs without checking and changing the settings, thereby allowing PUAs to infiltrate.
How to avoid installation of potentially unwanted applications
It is important to download software and files from official, trustworthy websites and via direct links. Peer-to-Peer networks (e.g., torrent clients, eMule), unofficial websites, third party downloaders, installers and other similar channels, sources should not be used to download/install software or files. Check 'Advanced', 'Custom' and other settings of the download and installation setup. Dismiss offers to download or install unwanted software before completing download/installation process. If clicked, intrusive ads that are displayed on dubious pages can open other, potentially malicious websites or cause download/installation of unwanted applications. Therefore, never click these ads. Note that they might also appear on legitimate web pages. Remove any unwanted apps (extensions, add-ons, plug-ins) installed on the browser immediately. Also remove software of this kind that is 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.
