  • Implement process protect mechanism to prevent the tool from being killed by ransomware.
    Note: WinXP x64, Win2003 x64 are not supported by this feature.
  • Less strict terms/rules to determine whether a file is a malware or not. As long as the file in registry autorun key has no digital signature, it will show suspicious. Because of this feature, the user should fix items on AR Tool carefully.
