Since 2015, ransomware occurrences have been growing 50% year over year, mainly due to success. Just alone in 2015, ransomware netted over $325 million from infected machines locked out of critical applications and data, and now this has spread to schools and even school districts. Understand ransomware and how it spreads, areas it can gain access to your systems, and more importantly prevention strategies. Just because you have antivirus on your machine, does not mean you will be fully protected anymore when it comes to ransomware.
