Came across this site while trying to gain more knowledge about this host file thing. Could be a good place.
Goals
This project has the following goals:
* To make available for free a centralized and automatically updated list of URLs that point to Malware. These lists can be used by system/network administrators to block user access to infected addresses. With the access blocked the risk of users getting infected by viruses is greatly reduced.
* To enable users and administrators to easily contribute to the Malware Block List including new URLs suspected of pointing to Malware.
* To alert administrators of hosts, domains and AS for the presence of Malware. Administrators are urged to removed the Malware found and to investigate the criminal activity that may be under way.
* To consolidate statistics about Viruses, Trojans and Worms that are at large.
* To list domains that host Malware.
