along with the 1000s of sources that could possibly carry ransomware, we now seem to have something new on the scene. Or maybe it has been around awhile but this is the first I have seen of it.
If you open an infected email or an infected file, then it will change all your file extensions to .TRO and you will not be able to access these files or change the extensions.

If you also have a external hard-drive connected to your PC or Laptop, then any files on there will also be affected.
So keep your antivirus programs updated guys... stay save.

If you get something like this or any virus infected file, then use the website coded and shown below. That website is sponsored by Malwarebytes, which is 100% trusted
