Avast detects this as Win32:WinVNCbased-F because it is looks upon it as a RAT (Remote Administration Trojan),
because VNC is a Remote Administration program often used to remote into other systems, and
may have come in on the back of other malware...this type can be a slight modification of an older type,
as the program could be considered a "risktool" for those that have not installed it intentionally,
the downloadsite is clean: sucuri scan for /http//wXw.trustware.com/ gives an all green...status:
Site verified to be secure and free of malware.
web trust: Site not blacklisted; also found clean here:

P.S. Pondus - reanalyze the virustotal.scan - it now only has the avast detection of this "risktool" find...
so -Result: 1 /41 (2.4%)
