校园网病毒防范系统的实现与改进

计算机病毒的广泛传播，严重威胁网络运行的安全。安装防病毒软件是一种最常用的预防病毒入侵的手段，但是受病毒攻击、黑客攻击、操作不当和软件安装冲突等因素的影响，经常会导致运行于后台的防病毒软件运行异常，失去防毒功能，而这个过程一般很难被使用者察觉，导致病毒的泛滥。这里针对上述过程设计了对防毒系统运行和升级状态进行实时监控的模块，该模块可在防病毒系统运行异常时，及时通知用户采取应对措施，防止计算机病毒进一步的蔓延，保证计算机网络的安全运行。

The Realization and Improvement of Antivirus System for Campus Network

Network security is seriously threatened by distributed computer virus. Most common methods to prevent computer virus invasion are to install network based anti-virus software system. But several factors including virus attack, hacker,improperly operation and software conflict cause backend anti-virus program out of normal operation and functional disability. The process is hard to be observed by users, thus the virus is booming. Designed module for real time monitoring anti-virus system status and upgrading status, can notice user to take proper action when system become abnormal, prevent computer virus further spreading, then protect computer network in the safe mode.
