Have you guys seen or tested out the new version of comodo's valkyrie service? https://valkyrie.comodo.com/home Valkyrie is a cloud based malware detection service which uses many different detection techniques including behavioral analysis, machine learning, and heuristics. The new version is not final yet and is still being worked on. They are still adding new detections too but try it out it seems to work very well.
Didn't knew new version is there. Your link takes to login screen. Previously Valkyrie didn't require login.
Still buggy.... 1) I want to re-analyze the file and got error message. 2) Static analysis says malware and dynamic unknown...yet the final result is unknown?
1. They are still working on bugs and improvements. This version is more of a beta 2. I remember asking about this with the old version and they told me its not just based on one detection mechanism, they use many complex algorithms to make the final decision. Just because the file acts like malware doesnt necessarily means it is malware. There are overlapping actions between safe files and malware.
Iv been in contacting with one of the developers and they think they should have a more stable release in the next week or 2.
