不知道为什么，电脑里的照片档、图片档，
都打不开，而且副档名都变成.yutrfnhd
原本存放照片的资料夹还出现一个文件档，
里面写
all your document photos databases
files are modified only.The modification
is reversible.
The only way to decrypt your files is to receive the private key and decryptio
n program.
And attempts to restore your files with the third party software will be fatal
for your file.
然后还叫我去下载Tor Browser
请问，这是中毒吗？
