(With the development of the Internet, network security issues emerge one after another. Over the years, computer viruses, worms, and attack-induced losses have become the most widespread security threats. Calculations show that in the field of information security, enterprises invest the most in antivirus, but viruses are still the biggest security threat. As for enterprise users, when they suffer from these threats, it often causes data damage, system abnormalities, network paralysis, information theft, reduced office efficiency, and direct or direct economic losses. Especially in recent years, there has been a clear upward trend of viruses with direct intentions of money and interests, and it is threatening the economic interests of enterprises. Users reading on the Internet, downloading via FTP, instant messaging, and using U disks have all become methods of virus transmission. Other problems such as hacker attacks often follow viruses. On the whole, the virus threat has emerged as a hybrid, networked, and increasingly fast threat. Faced with the threat of viruses under the new situation, the traditional anti-virus products' isolated and single-point deployment prevention mode can no longer meet the needs of anti-virus. Anti-virus technology urgently needs to build a united front that combines various technical techniques and management methods.)
