Just ran a "super scan" with ZAX (Extreme) and it put the file ffmpeg.exe, which was part of "any video converter" from AnvSoft, into quarantine.
I believed it was a false positive so ran it through virustotal.com, file had been examined before, and NO malicious code was found, here is the report
summary of report:

I've reported it to Kaspersky as a false positive so ZA products should be fixed soon hopefully.
