被加密后文件拓展名为gerosan的病毒,联系邮箱为[e-mail],[e-mail],

昨天（2019.6.11）发生了一件很不幸运的事情。windows 10系统右下方显示系统没激活，我就到网上去下载了一个所谓的windows数字激活的工具。解压压缩包后，双击了exe文件，显示工具有更新版本，让我更新工具。结果我发现它搞了一段时间都没下好，还在帮我安装软件。意识到是病毒，立马强力卸载它安装的几个软件。一会弹窗显示windows10系统在更新，从窗口外观真的像在更新系统。过了一会，又频繁地打开网页，桌面也在频繁的刷新，估计此时正在加密我的文件。我有点慌，想打开强力卸载的工具卸载它安装的软件，发现卸载工具被改了拓展名打不开了，其他的文件也如此。我又联网下载了360安全卫士，想着如果是老病毒可能管用吧。下载完360卫士把网线拔了，怕它在局域网传播。仔细看盘，发现了它勒索的文字，让我用比特币购买解密软件和密钥。我慌了一会就向我们老师报告了这个事件。我回到宿舍向勒索的邮箱发了一个邮件，第二天早上得到了回复，也向学校网络安全中心报告了这个事件。 它的勒索文字如下：
