Dynamic remote malware scanning

A method of detecting malware on a client computer, the method including generating a hash of an entity at the client computer, whereby the entity is suspected to be malware, sending the hash to a network server, considering the reputation of the hash at the network server by comparing the hash to a database of hashes of known reputation, returning the results of said considering to the client computer, and, if the reputation is not known at the server, sending instructions to the client computer for obtaining further information about the entity at the client computer, wherein said further information is obtained by executing code at the client computer sent by the server to the client computer after said considering the reputation if said code is not stored at the client computer before said generating a hash.
