3. If you're on another system and you haven't closed port 445 or patched your system, there's a good chance you'll get it.
Question 3: What is the depth of the "ransomware"?
The new version of the computer housekeeper's toolbox has such a good immunity tool
After installation, open the toolbox, you can see a ransomware immunity tool
