Hi true indian,

You could send the suspicious link to virus AT avast dot com and as long as the link is up and alive they can run the binairy analysis and add detection if found to be malicious.
The analysts should have received them anyway through the channels they use as resources, but some av take a couple of days to be "up to the mark". That is called the vulnerability gap, and it should not be left open too long. Av-solutions are not always overlapping and sometimes complementary. Just check the links you gave here: http://online.us.drweb.com/?url=1 and you see a lot of those you come up with are detected. That is why I have it as a complementary scanner next to avast web rep.
I assume the way Tech intended this thread is to add to detection in a way that one has/downloads a particular undetected file in zipped format and password protected and then send it to virus AT avast dot com with the password to be analyzed and eventually be added to detection. If you want to do that, you should have the VM lab settings for it, know how to work malzilla for instance and run a file in a sandbox environment. You should  know how to block script running and be able to determine when to click links or not and you should feel security aware enough,

Hi true indian,

Well Pondus and polonus are not the same, but they are cooperating here to analyze malicious URLs etc. Pondus gets a lot of information from polonus and polonus gets a lot of information from pondus. And there are more users in this particular group of conaisseurs, as there is Asyn, Dim@rik, spg SCOTT, and a couple of others,
