This is a simple virus with an uncommon activation routine: on some machines, it turns the the BIOS boot-up password on and changes the password to 'monica'.
Do not confuse this virus with Monika.686, which is a totally different virus.
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.
