Why is this still a thing?
The Reg had an article on anti-ransomware techniques years ago. For individual PCs (not on a Windows domain) they (or possibly a commentard) pointed to FoolishIT and their free CryptoPrevent software. FoolishIT is now called d7xTech and their free version of the software is now on an obscure corner of the website (or was last time I looked.)
Or you can, umm, just not use Windows.
Anyone in a corporate environment should not have a problem. (Again, details on how to protect corporate machines was in original article.)
This whole ransomware scourge saddens me.
Biting the hand that feeds IT
