小红伞的avshadow.exe进程

小红伞V10新增了进程avshadow.exe，很多人认为这是小红伞ProActiv(主防)的进程，后来我发现卸载ProActiv(主防)后该进程依然存在，所以这个进程应该与ProActiv(主防)没有关系。下面是小红伞官方论坛关于该进程的解释：

dllhost.exe, msdtc.exe are Windows processes.
avshadow.exe blongs to AntiVir when running Scanner

This process is our implementation of the Shadow Copy Service
(something offered by current Windows Versions). It is used to scan
files that are locked or in use by creating a "shadow copy" of the file,
which:

a) allows us to scan it
and
b) does not interfere with any processes continuing to modify the "original" file.
 

大意为：该进程是对映像拷贝服务的实现，用于被锁定文件的扫描或通过创建文件的映像拷贝实现以下目的：1).允许扫描该文件；2).不干涉任何进程对“原始”文件的修复。
