Hello for all,
Just to close this thread, I would like to say that I contacted Sucuri, but the annual fee is prohibitive for me, since the blog is not for profit, just a hobby. So I decided to disable the blog so that the Trojan no longer affects any computer.
Many thanks to everyone here on the forum for all the tips and help. I learned some things that will help me in the future.
Greetings form Brazil!
