求救，中病毒老，怎么解决
双击硬盘打不开，右键打开最上面是自动播放，下面是打开，再下面是搜索，然后下面又是打开，后面的就正常了，每个盘里多了autorun.inf和RUN.EXE两个文件，是隐藏的。从中毒后每次开机就会出现NSIS ERROR错误
The insaller you are trying to use is corrupted or incomplete.
This could be the result of a damaged disk,a failed download or a virus.
You may want to contact the author of this installer to obtain a new copy.
It may be possible to skip this check using the/NCRC command line switch.
(NOT RECOMMENDED)
我删除了病毒文件，可重新启动后又这样，开机还是NSIS ERROR错误，还有很多软件打不开了
