Brief Description 

    

AntiCMOS.A is a boot virus that infects the boot sector of floppy disks and of hard disks.

AntiCMOS.A infects the hard disk of a computer when it is booted from a floppy disk that is infected with this virus. From then on, all of the floppy disks used on that computer will be infected and it will have problems starting up.

AntiCMOS.A is not considered a dangerous virus. Although it has been designed to delete CMOS information and the hard disk configuration, these actions are not carried out due to some bugs in its code.
