微软正在研究一种“友好蠕虫”,可用于快速升级软件补丁

新科学家网站报道,微软研究室的科学家们正在研究一种类似蠕虫病毒传播的方式,这种方式可使软件补丁升级更有效。Milan Vojnović是项目的主要负责人。

蠕虫病毒通过自身复制进行传播,当感染一台电脑以后,病毒自动探测工作组(group)或者子网(subnet)中的其他主机并传播。Milan所做的工作是利用类似的方式,让“有益的信息”自动在子网中传播,比如软件的升级补丁。这样做的最大好处是,不需要一个中央服务器提供补丁下载,补丁在电脑之间自动传播,速度更快,而且能够减轻子网内部的流量负担。

这种“友好蠕虫”比一般的蠕虫传播更有效率,它可以在一定时间内自动探测,并选择未被感染电脑最多的子网进行传播。友好蠕虫甚至可以预测蠕虫病毒将来怎样传播,提前进行防范。当然,这还有许多工作要做。

这一研究论文将在4月召开的第27界计算机通信大会(27th Conference on Computer Communications)上发表。

Friendly ‘worms’ could spread software fixes

(via newscientist.com) Microsoft researchers are hoping to use “information epidemics” to distribute software patches more efficiently.

Milan Vojnović and colleagues from Microsoft Research in Cambridge, UK, want to make useful pieces of information such as software updates behave more like computer worms: spreading between computers instead of being downloaded from central servers. Read more.

电脑运行情况一目了然,包括恶意程序

Runscanner可以让你知道你的电脑上正在运行的所有程序、服务、自动启动项,还有恶意程序,并且用红色鲜明的标出那些有问题的东西,你可以选择删除或者修复(慎重!)。操作界面见下图,点击看大图。

不过Runscanner郑重提醒大家,在决定做什么之前,最好到相关论坛里,让专家们把把关,看看runscanner的检测报告,因为如果误删的话,可能会导致很严重的问题。也正因为如此,runscanner为用户提供了3种级别,初学模式、典型模式和专家模式。在初学模式里只能检测,下载报告,可是不能采取行动。

Runscanner,免费软件,下载无需安装。使用时慎重!
