使用Mem工具查看纯DOS下系统内存使用情况,发现：
1. Boot From Floppy: Memory used 588K, Memory free 2086,524K
2. Boot From HDD: Memory used 2086,687K, Memory free 497K
说明HDD已经中毒，请教高手如何查杀该类病毒

最好把你 MEM 命令的详细结果列出来，MEM/C 、MEM/D

现在还能见到“活的”DOS病毒，绝对是一大幸事！

可以试试DOS下的江民KV300，可杀300种DOS病毒，它绝对是DOS下最强的杀毒软件：

我建议在Windows下查杀一遍病毒(楼主也可以先试试KV300、MSAV等等DOS下的杀毒软件)，然后删掉DOS的所有文件，然后重装DOS。现在重装DOS多方便啊，有软盘版、光盘版，还能和XP双启动。

这个是你从硬盘启动后的内存状况？

看不出有内存占用有什么异常，不存在什么内存被耗尽的问题，但我比较奇怪为什么有多个 FILES ？
