Returnil Virtual System来自欧洲著名的安全公司Returnil SIA,它是一个基于虚拟机原理的新一代防毒防木马类软件,可以瞬间把您的计算机用隔离罩保护起来,同时用一个内存中的虚假替身“影子”系统来接管真实的操作系统,任何病毒和木马都被限制在虚拟系统中使用,无法感染你真实的操作系统.重启后,所有危险即刻消失的无影无踪.常见的杀毒软件几乎对于每个文件操作,每个网络访问,每个注册表操作,都要盘查过问,同时用多达几十万的病毒标本进行逐一比较,这样下来系统的资源大部分被杀毒软件占用了,常常让您的爱机变得其慢无比.Returnil虚拟影子系统最高时只占用1%不到的系统资源,而且在空闲时几乎不占用系统任何CPU资源.同时,Returnil虚拟影子系统无需频繁的升级病毒库,一次安装,永久有效,是新型的防毒免疫类产品. 
 
Returnil虚拟影子系统支持包括中文在内的10种语言,界面极其简单朴实,操作非常方便快捷.无需重启电脑,一个按钮即可让您的爱机进入“影子”保护模式,为您的网络冲浪,学习工作保驾护航.

Returnil虚拟影子系统支持XP,2003,Vista等操作系统,支持RAID等磁盘阵列体系,同时兼容IDE,SATA,CF卡等硬盘设备.

新功能:加入了MBR保护功能,可以在保护系统分区的同时,保护MBR和第一磁道的安全.

注:在“改变工作模式”选项中选择“保护模式”即可使Returnil在每次开机后进入虚拟状态.
