Adware.CrossRider – What Is It and Why Are My Applications Frozen?

The Crossrider unwanted application is being effectively distributed via freeware installers and bundled packages. You can get your Mac affected by it without even being aware, that the Crossrider has installed on your machine with a freeware installation or bundled package. You might avoid this, by unchecking options under the Advanced or Custom tab of an installation suite. Visiting suspicious sites might get adware installed to your Mac.

The application seems to also have a Windows variant which is quite older and is named as Adware.CrossRider.Win32.35, but both operating systems are being targeted to this day.

Crossrider is a potentially unwanted program (PUP). It is known to have been connected to lots of applications which are considered PUPs and also pushes advertisements along via other applications. Crossrider is known to show advertising pop-ups and freeze your Mac applications.

MacOS:Bundlore-AT [Adw] is the other detection name for Crossrider. MacOS:Bundlore-AT [Adw] affects both MAC operating systems as well as Windows OS. MacOS:Bundlore-AT [Adw] is quite the old adware but it is still found nowadays as some older bundled application installers have the MacOS:Bundlore-AT [Adw] setup inside them.

In addition the adware can also be installed by posing by the premise that it is an update for Adobe’s Flash Player as seen in the screenshot below:


Crossrider could show a reasonably convincing, but fake variant of the normal OS X dialog message box which says that no suitable app is installed. All similar programs have a valid, Apple-provided developer certificate, thus macOS will install them without prompting a warning or a notification of any sort.
