Description DeadBoot.446
This is a very dangerous memory resident encrypted multipartite virus. It infects the MBR of the hard drive and overwrites boot sector on floppy disks as well as headers of EXE files that are copied to floppy disks. The virus encrypts the directories sectors on the hard drive, as a result after disinfection they stay not accessible. To detect its TSR copy the virus uses INT 13h call with AX=DEADh.
