Yesterday a friend of mine had his Windows 10 laptop infected with Zepto. This thing is so nasty and I cannot open the files with any type of program. Then I read a post saying they were encrypted and it would take a lot of time even for powerful PCs to decode this. So I found a security forum (sensorstechforum) claiming data recovery software might help with at least some of the files if you havent reformatted Windows. What do you think?
