Hello again!
Today i was attaked by ransomware (at least i think this is ransomeware because Cybereason RansomFree reacts on it).
In a nutshell it creates hidden folders with files. If i delete them - they appear again. My kaspersky free didnt see anything, so does EmsisoftEmergencyKit.
I reinstalled windows (from 7 to 10) - problem still exist. My next step - check for viruses with kav_resque_disk 10.
I will put the files and screenshots for research.
Files

 

Screenshots:

*Files:

*Cybereason RansomFree reaction:

Also i have(on windows 7) unplugged storage device with virus files. On windows 10 i didn't see it.

The folders were created by Cybereason RansomFree and are commonly misidentified by users or incorrectly reported as being related to malware...see these related topics.

If you attempt to delete these files and folders, RansomFree will re-create them.

The use of trap (bait, canary) files and folders is not a 100% solution...some data files probably will end up being encrypted by ransomware but whatever helps with prevention, I consider useful.

Thank's for help.

That's why Cybereason RansomFree reacts on explorer.exe - because I deleted his honeypots with explorer.
To be sure on 93%, I deleted Cybereason RansomFree - as a result, hidden folders disappeared.(Of course I installed it again)
