I had a virus on my computer "fydn7tfx3w2ei9m.exe" that Norton Security detected as unknown SelfHijack!gen1 while as I realise that most of my files are encrypted/changed with the extension Y70yt0.
In every folder affected by the virus is a .txt file "how to decrypt files.txt" with this message:
You broke the law, all of your files are encrypted! To decrypt files you need to write an email to: firstname.lastname@example.org or email@example.com
In the letter you need to tell us your country of residence and your ID.
Services decoding paid. The cost depends on the country. Please do not write if you do not intend to pay.
On checking, you can send us a 2-3 small encrypted file (up to 3 megabytes each) and we decipher them for free.
Your ID t7435058
I dont know what decrypt tool to use, I tried some but without success.
Please I need some help to recover my files.
