卡巴斯基悲催:美国全力封杀全球第一杀软

虽然在AV-TEST最新杀软评测中,卡巴斯基得到了满分成为第一,但美国依然不允许它出现在政府采购名录中,而这个封杀的事态还在加剧。

据外媒CNET报道称,除了美国的政府机构外,FBI也在悄悄暗示那些私营机构停止使用卡巴斯基,情况十分严重。

报道中提到,能源行业以及使用工业控制系统等企业,都在被警告的名单中,而按照美国的意思,就是先让该国企业尽可能快的从其系统中移除卡巴斯基。

虽然卡巴严正否认自己进行涉嫌收集不法信息的“间谍”活动,甚至可以交出软件源代码,但目前的情况是,这丝毫没有打动当局控制者,而消息中还透露,俄罗斯也正努力移除美国科技公司如微软的操作系统。

对于微软来说,这件事他们暗地里非常开心,因为这样可以让更多的用户来换用Windows Defender,尤其是随着创意者更新全面升级的“新安全中心”。
