Brief Description 

    

KillCMOS is a Trojan that deletes the settings menu on computers. By doing this, the customized settings will be replaced with the factory settings.

This action can be either harmless or very dangerous for the affected computer.

For example, when the settings are deleted, the password that protects the configuration of the user’s computer will also be deleted. Therefore, any user will be able to access the settings menu and change the BIOS values. 

KillCMOS does not use any specific means to spread.

Visible Symptoms

In addition, on deleting the CMOS memory, it changes some data on the computer, such as the date, time, disk drives installed and characteristics of the memory and circuit board, among others. By doing this, the time will be 00:00 and the date January 1st.
