the source of av database


For curiosity, i have a question about the source of av database. I knew that some av vendors have their own servers to catch some virus samples, But there is a large signatures added everyday. May be the av vendors have another source to complete their everyday update. May be from the Wildlist. Could you tell me? :smiley:

Many Samples are uploaded by Special Forum Members, and Public Honeypots / Server.

Hope this helps
