Description: Intego has discovered a spyware application that is installed by a number of freely distributed Mac applications and screen savers found on a variety of websites. This spyware, OSX/OpinionSpy, performs a number of malicious actions, from scanning files to recording user activity, as well as sending information about this activity to remote servers and opening a backdoor on infected Macs. OSX/OpinionSpy is installed by a number of applications and screen savers that are distributed on sites such as MacUpdate, VersionTracker and Softpedia. The spyware itself is not contained in these applications, but is downloaded during the installation process. This shows the need for an up-to-date anti-malware program with a real-time scanner that can detect this malware when it is downloaded by the original application’s installer.
You will note that this is distributed the same way that most Windows virus's are distributed, by the user clicking on a free download. This also puts to rest that Mac users are more intelligent when it comes to security then Windows users. The issue here is that they feel because they own a Mac that they can do what ever they want,
