勒索病毒你最关心的13个问题 电脑管家做了回答

2017-05-17 07:52:26   华龙网

答:有效预防此次Wanna勒索病毒可通过以下行为进行规避。

一是,临时关闭端口。Windows用户可以使用防火墙过滤个人电脑,并且临时关闭135、137、445端口3389远程登录(如果不想关闭3389远程登录,至少也是关闭智能卡登录功能),并注意更新安全产品进行防御,尽量降低电脑受攻击的风险。

二是,及时更新 Windows已发布的安全补丁。在3月MS17-010漏洞刚被爆出的时候,微软已经针对Win7、Win10等系统在内提供了安全更新;此次事件爆发后,微软也迅速对此前尚未提供官方支持的Windows XP等系统发布了特别补丁。

三是,利用“勒索病毒免疫工具”进行修复。用户通过其他电脑下载腾讯电脑管家“勒索病毒免疫工具”离线版,并将文件拷贝至安全、无毒的U盘;再将指定电脑在关闭WiFi,拔掉网线,断网状态下开机,并尽快备份重要文件;然后通过U盘使用“勒索病毒免疫工具”离线版,进行一键修复漏洞;联网即可正常使用电脑。

四是,利用“文件恢复工具”进行恢复。已经中了病毒的用户,可以使用电脑管家-文件恢复工具进行文件恢复,有一定概率恢复您的文档。

另外,企业网络管理员可使用“管理员助手”检测电脑设备安防情况。腾讯反病毒实验室安全团队经过技术攻关,于14日晚推出了针对易感的企业客户推出了一个电脑管家“管理员助手”诊断工具。企业网络管理员只要下载这一诊断工具,输入目标电脑的IP或者设备名称,即可诊断目标电脑是否存在被感染勒索病毒的漏洞;并可在诊断报告的指导下,对尚未打补丁的健康设备及时打补丁、布置防御。

问:腾讯电脑管家应对此类敲诈者木马有什么办法?

答:针对于此次Wanna勒索病毒,腾讯电脑管家可提供漏洞防御,主动拦截,文档保护三层安全保护及文件鉴黑,同时紧急开发上线一系列工具协助用户解决勒索病毒问题:

1.使用电脑管家-勒索病毒免疫工具,关闭漏洞端口并安装系统补丁。

2.开启电脑管家实时防护,启用文档守护者功能,预防变种攻击。

3.已经中了病毒的用户,可以使用电脑管家-文件恢复工具进行文件恢复,有一定概率恢复您的文档。

4.针对企业网络管理员,可以使用“管理员助手”检测电脑设备安全防御情况,进行漏洞诊断、补丁更新和布置防御。

问:目前网上流传该木马病毒作者已经放出密匙是否属实?
