Did you find a file called syesubc3_p2v3.exe, digitally signed by Syndacato and wonder where it came from? I found this file in my Temp folder after installing uTorrent on my lab machine. Did you also recently install uTorrent, or did it come bundled with some other download in your case?

Update 2015-02-08: Now the file is called syesubc8_p2v3.exe.

What does the Syndacato file do? Appears it did nothing on my machine. It just terminated after I double-clicked it. SuperAntiSpyware detects the file, Symantec tags it with their “Reputation” flag. The other 54 anti-virus programs does not detect it when I uploaded it to Virustotal.
