Acanze.A is simple email worm of Italian origin written in Visual Basic. Due to the coding techniques used the worm will only work properly under Italian Windows versions.
Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.
Upon execution Acanze.A will create a hidden system file named 'login.bat' into %WINDOWS% directory. It will then set a registry key:
The key allows Windows to start the bat file each time a user logs on.
Under Italian versions of Windows additional files will be dropped and the attributes to both file set to hidden system.
The worm will then check whether a connection to an Italian site can be established. If so it will create email messages containing copy of its body and send them to recipients in Outlook's Contact list.
