我装的是WIN2000，256M内存。装了在这里看到的卡巴斯基后，一个星期后提示卡巴斯基反病毒数据库受到攻击，被破坏。卸载掉卡巴之后想重装，就老提示“CRC校验失败”，后用朋友解压过的卡巴安装，就提示“该软件已经遭病毒感染或下载过程已损坏”，安装仍然失败。用买的瑞星在线杀毒，在下载过程中也有同样的提示，所以瑞星在线杀毒也用不。之后从A盘启动用瑞星查毒，没有查出病毒。没办法现在重新装了瑞星，在安全模式下查毒，仍然没有查到毒。但是想运行或安装下载的软件仍然不断提示失败，似乎只要是下载的软件就不行。特把用hijackthis扫描的日志发上来，请高手们帮我看看，哪里可能有问题，是不是哪个系统文件被破坏了？
