It seems to me that every time a Ransomware attack occurs, it usually appears that we are once again incredulous that it happened, and we believe the AV (Anti-virus) companies should have figured this out by now. Right?  In reality, these cyberattacks appear to be something we will have to learn to live with.

I often go to PCWorld for advice when I want guidelines for dealing with a computer related problem.  Over the years I have found PCWorld to be succinct in their description of problems, and how to solve them. In addition PCWorld provides suggestions for computer software, PC equipment etc.

Eric Geier of PC World had this to say about Ransomeware as recently as April 3, 2017:

1. “…You can remove many ransomware viruses without losing your files, but with some variants that isn’t the case. In the past I’ve discussed general steps for removing malware and viruses, but you need to apply some specific tips and tricks for ransomware. The process varies and depends on the type of invader. Some procedures involve a simple virus scan, while others require offline scans and advanced recovery of your files. I categorize ransomware into three varieties: scareware, lock-screen viruses, and the really nasty stuff.
2. Removing ransomware. Before you can free your hostage PC, you have to eliminate the hostage taker. If you have the simplest kind of ransomware, such as a fake antivirus program or a bogus clean-up tool, you can usually remove it by following the steps in my previous malware removal guide. This procedure includes entering Windows’ Safe Mode and running an on-demand virus scanner such as Malwarebytes.”  Source: How to rescue your PC from ransomware | PCWorld
