Brief Description 


Agent.MIZ is a Trojan, which although seemingly inoffensive, can actually carry out attacks and intrusions.


Agent.MIZ prevents access from programs to websites of several companies related with security tools (antivirus programs, firewalls, etc.).


It uses several methods in order to avoid detection by antivirus companies:

  • It terminates its own execution if it detects that it is being executed in a virtual machine environment, such as VMWare or VirtualPC.
