What are pop-up ads?

POP-UP ads (or simply 'pop-ups) are advertisements that usually appear in smaller windows. Typically, they appear in the foreground of a visited website and thus often conceal underlying content. Their presence is due to installed adware or visited websites that use rogue advertising networks. However they are displayed, pop-ups are annoying and cannot be trusted.

Pop-up ads adware

If clicked, pop-up ads open dubious websites - for example, deceptive web pages that trick people into downloading unwanted applications. These sites often state that the visitor's computer is infected with viruses that must be removed immediately using various potentially unwanted apps (PUAs). Rogue pop-up ads sometimes run scripts that download and install PUAs.

To achieve this, however, they must first be clicked. There is a high probability that any downloaded or installed PUAs will be malicious. People are often tricked into clicking these ads when a fake 'close button' is applied to them. Rather than closing the ad, the click performs other unwanted actions.

Pop-up ads often appear due to installed adware - software used to generate revenue for developers by feeding regular users with unwanted ads. These PUAs serve users with various pop-ups, banners, coupons, surveys, and so on. If clicked, these ads cause redirects to dubious websites or installation of other unwanted apps.

The more ads are displayed, the more adware developers generate revenue. Generally, people download and install adware unintentionally. You are advised to remove all installed advertising-supported software immediately.

Some examples of apps classified as adware include MyCouponsmart, Top Results, and MatchKnowledge. There are many other apps of this type. They are advertised by offering 'useful' features, tools, and so on, however, when installed, they deploy ads and provide no real value.

To avoid redirects to dubious web pages, unwanted installations, or being served with annoying ads, uninstall all adware-type apps immediately.

How did adware install on my computer?

Typically, adware-type apps (and other PUAs) are distributed using deception. Developers bundle them into set-ups of other software. Therefore, they are installed together with other programs. Information about these additionally-included apps is not properly disclosed.

Generally, information about bundled apps can be found in download or installation setup settings such as "Custom", "Advanced" and other similar parts.

Unfortunately, not all people check these settings and thus allow PUAs to be downloaded and installed without their knowledge. In other cases, unwanted apps are installed through deceptive ads that are displayed on dubious web pages. If clicked, they execute scripts that cause unwanted downloads and installations.

How to avoid installation of potentially unwanted applications?

Avoid downloading software from untrustworthy, unofficial websites or using torrent clients, eMule (other Peer-to-Peer networks), and so on. We advise you to use direct download links and official websites. Do not skip download or installation setup steps without checking the "Custom", "Advanced" and other similar settings and options.

Opt-out of additionally-included/bundled software and only then proceed to the next step or download/installation process. Typically, intrusive ads redirect users to untrustworthy/potentially malicious websites, especially if they are displayed on web pages relating to gambling, pornography, adult dating, and so on.

Do not click these ads. If a browser shows advertisements or opens unwanted web pages, check installed applications on the browser (extensions, add-ons, plug-ins) and remove all unknown/unwanted entries immediately. Additionally, if there are any unwanted programs installed on the operating system, they should also be removed.

If your computer is already infected with Pop-up ads, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
