Free apps install spyware on Macs

Mac users downloading free screensavers and a video converter app from several popular download sites also got spyware that installs a back door, collects data, and sends encrypted information to remote servers, security company Intego said on Tuesday.

The high-risk spyware, dubbed OSX/OpinionSpy, was being installed along with nearly 30 screensavers developed by a company called 7art and an app called MishInc FLV to MP3, according to a list compiled by Intego.

They were found on Softpedia, MacUpdate, and CNET-owned VersionTracker, according to a post on Intego's Mac Security Blog.
