Nasty for positive, but you’ll be able to take a number of steps that may vastly scale back the chance of it occurring to you. Our lately printed Ransomware Safety Information breaks them down for you, and on this weblog we’ll have a look at a number of the reason why ransomware safety is so important.
How unhealthy is ransomware, actually?
The brief reply is fairly unhealthy—to the tune of billions of {dollars} stolen from victims every year. Ransomware targets folks and their households simply as defined above.
