木马是颇具危害性恶意的程序。如今的木马在网络中四处传播,已成为网络用户最大的危害者。木马研究者为了有效查杀网络中的各种木马而提出了各种算法,这些算法在一定程度上能够有效地应对网络中的木马。但目前查杀木马的技术仍然落后于木马技术的发展。因此,为了进一步地提高查杀木马算法的智能性,提出一种基于粒子群的木马检测算法,该算法对现有的查杀木马技术能够起到一定的补充作用。 Trojans are quite harmful and malicious programs. Today’s Trojan spread in the network, has become the biggest harm Internet users. Trojan researchers in order to effectively killing all kinds of Trojans in the network and put forward a variety of algorithms that to some extent, these algorithms can effectively deal with Trojans in the network. However, the technology currently killing Trojans lags behind Trojan technology. Therefore, in order to further improve the intelligence of Trojans killing, a particle swarm-based Trojan detection algorithm is proposed, which can complement existing Trojans killing techniques.
