After installation of latest version of Anti-Ransomware, the first automatic start of the daily remote backup with Mozy (by iTOK) has been messed up. The software could not recognize the files to be stored remotely and the total amount of data to be saved was totally wrong - actually Mozy software encrypts files before remote transfer at 256-bit, which was supposedly seen ss ransomware activity.
Also, the printer was no longer found by any application, and PowerPDF (by Nuance) could no longer start.
Restarted the system in Safe Mode and uninstalled Anti-Ransomware with Ccleaner. The system worked well again and immediately.
