Well I submitted a sample to both camas.comodo and filterbit so you can compare the results against one and other.
The results for comodo look comprehensive, certainly enough to gauge that the file is malicious (which I know it is), see
camas.comodo analysis results. This is a little like the Anubis
http://anubis.iseclab.org/?action=home scanner providing a detailed analysis of the file and not just running it against multiple scanners.
Whereas the filterbit scan is of less value, being more like virustotal but with a very limited scanner set, see
filterbit scan results only 2 of 9 scanners found anything.
Control set from VirusTotal for comparison, an old scan 10 May 2009 on this file found nothing (0/39), so filterbit did a little better. However a new VT scan today shows 17/39 detections, see
VT results.
So filterbit doesn't compare well against VT in either the scanners in its set or the detection levels.
