This morning when I turned my other computer on something odd was on my desktop. It was labeled RecOveR and a window popped onto my screen that said there was a problem with my computer and in order to get access to my important files (there are none on the computer) that I needed to start getting bitcoins and pay to get them back. Has anyone heard of this attack !! Odd thing is it infected my photo imaging program and my SD card. Wiped out all my pics which is no biggie but my antivirus and windows defender is not picking this thing up. Anyone know what it is ?
