Downloaded the file, sent it to VirusTotal, here's the analysis.
Virustotal.This one is real.
Don't run it, unless you are geared up to do that.
The file name is "ctfmon_lr.exe". Surprisingly, Gdata detects as trojan generic. MBAM detects it as a Trojan Generic.
Not really prepared to run it to see what it does, sorry, but I am about to email it to Avast.
Thanks to the OP for advising of this.
If you are able to say what computer behaviour or symptoms of infection resulted from having this, and where you got it, that would be good.
