Eset Cyber Security Pro Sees Utorrent As A Malicious App. Is That Normal?

[tmrd]

I've downloaded Utorrent from its official website and installed it on my Mac, but after a day, Eset gave me a warning states that Utorrent.dmg is "dangerous", and I followed the standard procedure and deleted it. To make a test, I downloaded Utorrent from its official website and Eset deleted it again.

 

Here is the image:

"a variant of OSX/Adware.Spigot.A Application"

 

 

Should I worry?

 

P.S. I can use Utorrent, there is nothing wrong with the application. But setup file was deleted by eset, so I thought I can ask this question the community.
