How OXAR Ransomware Virus Penetrates the System

The OXAR ransomware infection is triggered by an executable file running on the system. It is called Data_Locker.exe and controls all malicious actions performed by .OXR file virus. In addition the ransomware may drop other malicious files on the system to complete all stages of the infection. These malicious files may be dropped or created in following folders:

    %UserProfile%
