<p>The present invention discloses an anti-virus implementation method for a proxy gateway, a pre-classifier and a proxy gateway. The method includes: receiving a resource obtainment request for obtaining resources to be transmitted; sending a pre-detection request to the network element where the resources to be transmitted exist according to the resource obtainment request, so as to obtain attribute information of the resources to be transmitted; based on an anti-virus strategy, judging whether the resources to be transmitted need anti-virus scanning according to the attribute information, if so, performing anti-virus scanning for the resources to be transmitted which are obtained later, and if not, transparently forwarding the resources to be transmitted which are obtained later. The present invention provides a technical solution which can pre-detect whether the resources to be transmitted need anti-virus scanning. The resources to be transmitted are pre-detected by using the attribute information, and the resources which do not need anti-virus scanning can be directly and transparently forwarded before being sent to a proxy layer, and therefore, the anti-virus function is realized, as well as the transmission efficiency can be improved, and the waste of the buffering, scanning and upper-layer transmission resources is reduced.</p> |
