FIELD: information technology.

SUBSTANCE: method of detecting malicious entities distributed over peer-to-peer networks consists of the following steps: requesting metadata relating to an unverified download entity from a control module at a peer-to-peer network server using a peer-to-peer network client of a user computer system. Further, the control module at the peer-to-peer network server determines availability of an antivirus module on the user computer system. Metadata relating to the unverified download entity are then downloaded using the peer-to-peer network client of the user computer system having an antivirus module. A download entity corresponding to the downloaded metadata is also obtained using said peer-to-peer network client of the user computer system. Malicious entities are also detected by checking the download entity using the antivirus module of said user computer system.

EFFECT: high level of security of a user computer system from malicious entities distributed over peer-to-peer networks.
