Dont be so harsh
Most of the victims are not IT savvy, you cant blame people for that.
The ransomeware plauge has made me change my back up plans, especially as malware now deals with networked drives etc.
So i now have 3 back ups, the cost of a 3tb drive is small enough to justify the cost and my songs, pics and docs which i have collected since i was using my Amiga are more precious to me than a 90 quid hard drive.
People need educating, not berating for not being IT savvy. Remember, some of these non IT people are surgeons, solicitors, scientists. Not understanding malware does not automatically mean they are not intelligent.
