Chill is a memory-resident virus which infects COM files on execution. Virus code is encrypted with a 8-bit variable key. The virus contains texts "[CHiLL TOUCH]" and "You cannot touch these phantoms". The virus also contains an activation routine which formats part of the hard drive.
Once detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.
More information on scanning and removal options available in your F-Secure product can be found in the Help Center.
