Intego has been monitoring the actions of the different versions it has found of the OSX/OpinionSpy spyware. We have discovered that, after a certain time, the spyware makes an “upgrade” and installs another application, which is another variant of the same spyware, called PermissionResearch. (It is also possible that further versions of this spyware will upgrade themselves to other variants.) Intego has updated its threat filters today (June 2, 2010) to improve proactive detection of this type of spyware. We strongly recommend that all VirusBarrier users update their threat filters immediately.
