OneHalf.3544 is a boot virus that infects the boot sector of floppy disks and hard disks. In addition, it also infects files with COM, EXE and SYS extensions.
OneHalf.3544 is very dangerous because it slowly encrypts the hard disk information, preventing it from being read by the system.
OneHalf.3544 infects the hard disk when the computer is booted from a floppy disk that is infected with this virus. From then on, all of the floppy disks used on the system will be infected and the computer will have problems starting up.
The main visible symptom of OneHalf.3544 is that infected computers have problems starting.
