为什么会这样?请各位高手指点迷津,多谢!

近期杀毒软件检测到电脑有一个漏洞---KB975561(该漏洞可能允许远程执行代码)。该漏洞很顽强,修复不了。一旦点击修复,电脑要么卡死要么出现蓝屏,蓝屏内容如下(
a problem has been detected and windows has been shutdown to prevent damage to your computer.
if this is the first time you have seen this stop error screen ,restart your computer.if this screen appears again,follow these steps:
check with your hardware vendor for any bios updates,disable bios memory options such as caching or shadowing.
if you need to use safe mode to remove or disable components,restart your computer,press F8 to select advanced startup options, and then select safe mode.
)。望各位高手拯救!
