Nope, I haven't experience that virus but I'm hoping that it won't attack my laptop. I already have experienced minor virus and it is like a nonstop insect that won't stop moving my files into different folders.
I had similar messages appearing on the browser, but not on the computer itself, so I never experienced a ransomware virus. I had my antivirus removing ransomware, but they were never active, it seems.
This is for the first time I am hearing about such Virus. I have never faced any problem so far with any virus! Happy to know that you could get rid of it by resetting your computer1
Never encountered that kind of very dangerous virus. How did it managed to get into your files is the question. With or without antivirus for your safety net.
