Just downloaded "µTorrent Stable(1.8.7 build 37979)" - and routinely ran it through virus barrier.
It's got "OS X/Spigot.A" according to Virusbarrier.
Beware. I'm officially a permanent non-uTorrent user.
This is a clarification, not a contradiction. I note that that you did not name the site from which you downloaded
µTorrrent 1.8.7. The omitted information is relevant as will become clear below.
Spigot is an adware engine. We tend to think of adware and malware as the work of nefarious people and the just desserts of those engaged in bad computer practices. Over the last year or so, this has changed. Formerly trusted repositories of computer software now distribute
Spigot and other adware engines along with the software that you are downloading.
A particularly egregious offender is CBS Interactive--a division of the same company that brings you
60 Minutes and
NCIS. Popularly known as c|net Download.com, this has been one of the most popular and trusted repositories of software for Mac and Windows for decades. However, Download.com downloads an installer rather than downloading your software directly. If you read the small print carefully and opt not to accept the adware, then you will get a clean .dmg disk image file used by the developer to distribute its software. However, the default is to download and install the adware.
There is another rather pernicious strategy for distributing adware for the Mac. Certain sites are now setup for the singular and sole purpose to tricking the user to click on a "desirable" video. The site then claims that you must download a viewer to view the video. The only way to escape the download window is to kill the browser window. If you consent, then the site will download an adware infected version of
MPlayer X or another well-known video player.
In preparation for this response, I downloaded
µTorrent 1.8.7 directly from the uTorrent.com website. I scanned the mounted .dmg file using
AdWareMedic.
AdWareMedic did not detect
Spigot or any other adware. I also downloaded
µTorrent 1.8.7 using the CBS Interactive Download.com website. The site downloaded a copy of the
µTorrent .dmg rather than an installer.
Now that you understand why sharing the download site for the source of your infected software is important, would you mind sharing that information with us?
