More on OSX/OpinionSpy

The OSX/OpinionSpy/PremierOpinion story has unfolded rather more slowly than we're accustomed to seeing in the world of Windows (where PremierOpinion has been flagged as adware, spyware or "possibly unwanted" for quite a while.

As far as the 7Art screensavers are concerned, the last time I checked, the  screensavers themselves seemed to be clean, and allowing access to PremierOpinion was optional. I don't have access to a Mac right now, but I'll check again when I do.

In the meantime, I've added a section on OSX/OpinionSpy to the slow-growing malware information database at It's not a detailed analysis, but it includes several links to much fuller information.

    ESET added detection for HellRTS quite quickly, but still no Sig update for Opinionspy?  Why not?
    I search on the ThreatSense updates page everyday for the term " OSX" and the HellRTS is the latest OSX threat that has been added.

      I’ll check the status. But you can’t really go by the updates page to tell you what we detect. The last time I checked, some relevant links were flagged generically. Remember that this is a porting of a long-existing Windows program.
