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