The only sure way to counter any ransom ware is to create system images to external media and if you have pictures and important docs on any machine, it's imperative that you have external back ups as you could lose all of those anyway in the case of HDD failure.

No, I had it even after removing it, They disappeared after using the tweaking program.
I too continue to learn hard lessons.
One, keep an offline backup
two, don't download or visit sites without thinking more carefully about what you are downloading
three, consider using an email service online that captures all mails before they get sent to you from unknown senders.
four, go back to only texting with HTML formatting in emailing programs.
five, one cmptr for games, one for work
other than that, life is just great!
