Remove SimpleProExtension adware from MacOS

Also Known As: SimpleProExtension 1.0 adware
Type: Mac Virus
Damage level: Medium

What is SimpleProExtension?

SimpleProExtension is supposedly a useful tool that helps users to browse the web more efficiently, however, it is a PUA (potentially unwanted application) classified as adware. It redirects all online searches through its own URL address before forwarding to Google search.

In doing so, SimpleProExtension can gather users' search queries. Apps such as SimpleProExtension are known to track browsing information, display unwanted advertisements, and cause redirects to other search engines such as Yahoo, Bing, and so on.

SimpleProExtension adware

Adware-type apps feed users with advertisements - usually coupons, banners, surveys, pop-ups, and other intrusive ads. People who click them are often redirected to untrustworthy websites or they cause download/installation of other PUAs (some ads run scripts with this capability). Applications such as SimpleProExtension also operate as information tracking tools.

They record users' IP addresses, geolocations, URLs of visited websites, entered search queries, and other data relating to browsing habits. PUAs sometimes record personal/sensitive details. Developers send all data to other parties (possibly, cyber criminals) who misuse it to generate revenue.

Furthermore, PUAs often promote other search engines (search.yahoo.com and bing.com) and force people to use them rather than their default search engines. These apps can lead to problems with privacy, browsing safety, and so on. Do not use PUAs or have them installed. Therefore, we advise to remove SimpleProExtension immediately.

SimpleProExtension is developed by the same people who created other apps of this type such as Top Results and MatchKnowledge. Do not use any of these apps. People do not generally download and install these apps intentionally - they are usually tricked, since developers advertise them as legitimate and useful software.

How did SimpleProExtension install on my computer?

Most users download and install PUAs through intrusive ads (they run scripts that download and install them) or together with other software when developers use a deceptive marketing method called "bundling".

They bundle unwanted apps into set-ups of other programs and hide related information in settings such as "Custom", "Advanced", and so on. Furthermore, people download and install PUAs when they fail to check settings included in set-ups. In this way, they unintentionally allow PUAs to be downloaded and installed with other software.

How to avoid installation of potentially unwanted applications?

Download software from official and trustworthy websites (sources), avoid using torrent clients, eMule (other Peer-to-Peer networks), third party downloaders and so on. These channels are often monetized by distributing unwanted, potentially malicious apps. Do not skip setup steps without checking all "Custom", "Advanced" and other similar settings/options included.

Deselect offers to download or install additional software (PUAs) and only then complete the download or installation process. Do not click intrusive ads, especially if they are shown on dubious web pages. When clicked, they open other untrustworthy web pages or even lead to unwanted downloads/installations.

If you experience unwanted ads or redirects to dubious sites, this might be caused by adware or other PUAs.

Remove all unwanted extensions, add-ons, and plug-ins installed your browser and unwanted programs installed on the operating system. If your computer is already infected with SimpleProExtension, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
