Autorun.TG is a virus that spreads to other computers by copying its code to other files or programs.

It affects productivity, preventing tasks from being carried out:

• In the affected computer: .

It uses stealth techniques to avoid being detected by the user:

• It injects itself in running processes.
• It deletes the original file from which it was run once it is installed on the computer.
• It modifies system permissions in order to hide itself.

Autorun.TG uses the following propagation or distribution methods:

• Exploiting vulnerabilities with the intervention of the user: exploiting vulnerabilities in file formats or applications. To exploit them successfully it needs the intervention of the user: opening files, viewing malicious web pages, reading emails, etc.
• Computer networks (mapped drives): it creates copies of itself in mapped drives.
• Computer networks (shared resources): it creates copies of itself in shared network resources to which it has access.

Autorun.TG uses the following infection strategies:

• Resident: once it has been run, the virus goes memory resident and stops functions belonging to the operating system. Therefore, every time the operating system or an application tries to access any of these functions, the virus will activate and infect new files.
