Stop ads displayed by OnlyApplication adware

Also Known As: Ads by OnlyApplication
Type: Mac Virus
Damage level: Medium

What is OnlyApplication?

Developers advertise OnlyApplication as a useful tool which provides faster searches, accurate results, and an enhanced browsing experience.

In fact, this program is classified as a potentially unwanted application (PUA), an adware-type app that serves unwanted, intrusive advertisements. PUAs often collect various user-system information. Generally, people download and install adware (and other PUAs) unintentionally.

OnlyApplication adware

When adware such as OnlyApplication is installed on a computer or browser, it feeds users with unwanted, often deceptive advertisements. For example, coupons, banners, surveys, pop-ups, and so on. Typically, people who click these ads are redirected to dubious or even malicious websites.

Some of these ads might run scripts that download and install PUAs, or potentially malicious programs. Furthermore, installed PUAs might be used to gather various details such as users' IP addresses, entered search queries, addresses of visited websites, geolocations, etc.

Developers share the data with other parties who misuse it to generate revenue. Some of these third parties might be cyber criminals. Adware and other similar PUAs can lead to problems with privacy, browsing safety, and could even be used to steal users' identities. For these reasons, we recommend that you uninstall adware from browsers and computers immediately.

OnlyApplication is virtually identical to other adware-type apps, such as ExtraWindow, CoordinatorPlus, WindowMode, and many others. In any case, these apps serve unwanted ads and record various details.

They provide no value. To avoid possible problems that might occur due to adware, do not download or install PUAs and remove any installed on browsers or operating systems.

How did OnlyApplication install on my computer?

PUAs are often downloaded and/or installed through intrusive advertisements that people click, or during the download/installation processes of other software.

Developers include unwanted apps into the set-ups of various programs, however, they do not disclose related information - offers to download or install additional apps is hidden in settings such as "Custom", "Advanced", and so on.

This distribution method is called "bundling" - it is a deceptive marketing method that developers use to trick people into downloading and installing unwanted apps with regular software. It often works when people fail to check the settings that are available in set-ups, and leave them unchanged.

In doing so, they grant PUAs permission to be downloaded or installed by default.

How to avoid installation of potentially unwanted applications

All software should be downloaded from official websites, especially if it is free. Channels or tools such as third party downloaders, installers, unofficial, dubious web pages, Peer-to-Peer networks (torrent clients, eMule) should not be trusted, since they are often used to promote various unwanted, possibly malicious applications.

All files and software should be downloaded from official websites. Furthermore, if a download or installation setup contains any settings (such as "Custom", "Advanced"), check them carefully. They often include offers to download or install unwanted software.

These offers should be dismissed before completing the download or installation process. Do not click ads that are displayed on dubious web pages. Typically, they cause redirects to other dubious pages or cause unwanted downloads/installations. Note that ads of this kind might also be displayed on legitimate web pages.

To stop browsers from opening untrustworthy websites or showing unwanted ads, remove unwanted or suspicious extensions, add-ons and plug-ins installed on them.

Additionally, it might be necessary to apply this to programs of this type installed on the operating system. If your computer is already infected with OnlyApplication, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
