I FOUND A SOLUTION.
Sorry my english is bad.
The only thing that work for me are the following steps.
1 we must go to %temp% and delete everything in here.
2 I've download an antimalware (to delete the virus) , I dont remember the name but it's an program with a blue M.
This help a lot cause after the analyze i found 32 files with the virus. And of course I delete everything
3 after that the only problem left are the encrypted files.
Honestly I didn't find a way to desencrypt them, BUT lucky me I was able to make a recovery of them.
Go to a file, delete
