    • A system and method to securing a computer system from software viruses and other malicious code by intercepting attempts by the malicious code to write data to a storage medium. The invention intercepts the write access requests made by programs and verifies that the program is authorized to write before letting the write proceed. Authorization is determined by using the identity of the program as a query element into a database where permission values are stored. Depending on the presence or value of the permission value, write access is permitted or denied. Permission values can be set by the user, downloaded from a central server, or loaded into the central server by a group of users in order to collectively determine a permission value. The interception code can operate in kernel mode.
    • 一种通过拦截恶意代码将数据写入存储介质的尝试来保护计算机系统免受软件病毒和其他恶意代码的系统和方法。 本发明拦截程序所做的写访问请求,并且在进行写操作之前验证程序是否被授权进行写入。 通过将程序的身份作为查询元素使用到存储权限值的数据库中来确定授权。 根据权限值的存在或值,允许或拒绝写访问。 权限值可以由用户设置,从中央服务器下载,或由一组用户加载到中央服务器中,以便共同确定权限值。 拦截代码可以在内核模式下运行。
