勒索病毒求助。

5月1日晚，大量win10电脑资料被加密，添加统一后缀{73ABA010-D928-47FD-7DCB-72284ABD03AA}.restorebackup。每个文件夹都有一个readme.txt的文件，安装了360的电脑速度比较快的基本只被添加了readme.txt,资料文件少量被加密（如log，png等文件），速度比较慢的，被加密文件相对较多（部分Excel word文件），没有安装360，靠微软自带杀毒的基本全被修改（包括excel word txt bpl frf osd 用友数据库文件SQLserver等等）。win11系统没有感染，win7系统部分没有感染，另一个网段的电脑也没有感染。希望早日出解密程序。
readme.txt内容：

需要进行溯源分析，排查中毒原因。请添加2880706404，并备注被加密文件后缀。
